Abstract
This invention relates to a method of producing a recombinant eukaryotic heterodimeric enzyme using a prokaryotic host. The method involves constructing a first DNA vector containing DNA encoding one of the subunits of the dimeric emzyme and then constructing a second DNA vector containing DNA encoding the second subunit of the enzyme. Once the DNA vectors are constructed, they are used to transform a prokaryotic host. The transformed prokaryotic host cell is then cultured under conditions appropriate for the expression of the dimeric enzyme. For example, using the method of the present invention, the heterodimeric isoform of creating kinase CKMB can be produced. This invention further relates to a method of producing a recombinant human dimeric enzyme in an active form using a prokaryotic host, the recombinant enzyme products produced using the method of the present invention, and a transformed prokaryotic host constructed by the method of the present invention.

The GeneAmp PCR Reagent ~it with AmpliTaq DNA
Polymerase from Perkin Elmer Cetus (Norwalk, CT) was used for PCR reactions. The reactions were carried out following 2 5 standard procedures outlined in the literature enclosed in the kit Specifically, 5-30 ng DNA, 100 pmol primer DNA, 2.5 U AmpliTaq DNA polvmerase, and 200 ,umol dATP, dCTP, dGTP, dTTP were mixed with supplied buffer, and the reaction mix was overlayed with Ampliwax ( Perkin Elmer Cetus ) . The 3 0 PCR machine (Coy Laboratory Products, Inc . Grass Lake, MI) was ~L yL -d for ~ cycle of 94-C Lmelt) for 2 minutes, 55 C (anneal) for 2 minutes, 72 C (extend~ for 2 minutes, this cycle was repeated 1~3 times. A final extension step was run for 10 minutes to allow for complete polymerization 3 5 of all strands. PCR product (approximately 5-10 llg~ was digested with Ndel and EcoR1 ~for CKB~ or Ndel and BamH1 ~ for CKM) and purified by electrophoresis through a 0.7% low melting point agarose TAE buffered gel (FMC BioProducts, Inc. Rockland, ME~ for cloning into expression vectors.
40 Electrophoresis was performed as described in Molecular Cloning (Sambrook, Fritsch and M~n;~ti c, 198g. Cold Spring Harbor Press, Cold Spring Har~or, NY) . Restriction WO 95112662 217 rj S ~l ~ PC~IUS94/12624 endonucleases were purchased from New England BioLabs (Beverly, MA) and digestion reactions set up as suggested by the manufacturer. DNA fragments were purified from gel slices using the f.~nf~ An kit (BiolO1, La Jolla, CA~.
s Conqtruct;n~ thf~ S;~n - ~rnreccinn Vector r-R7~8 The expression vector was constructed at Genzyme as a derivative of the plasmid pBluescript SK +/-~available from Stratagene, La Jolla, CA). Expression is 10 driven off the Lac promoter. Our vector, pRZ38, was constructed by adding an restriction enzyme site at the ATG
start codon of the b-galactosidase gene through site-directed mutagenesis. Mutagenesis protocols were followed as described using the Muta-Gene In Vitro 15 Mutagenesis Rit from BioRad (Ri rl 1 , CA) . This change in the vector allows cloning of foreign genes after the LacZ
promoter but maintains similar spacing from the promoter as in the native gene.
20 ('lnn;n~t CKM ein~ CKR nN!~ ;nt~ R7~8 Vector DNA (5 llg) was digested with Ndel and EcoR1 (for CKB) or Ndel and BamH1 (for CKM~ and gel purified as above. Approximately 100 ng digested vector DNA and 100 ng digested PCR product were ligated in a 20 111 reaction (T4 25 DNA ligase purchased from NEB, Beverly, MA) . Ligation reactions set up as described in Molecular Cloning. After overnight ;n llh~t;nn at 15 C ligation mixes were diluted to 60~1 with dlI20. 1111 of each was electroporated into electroporation competent E. coli strain MC1061. The 3 0 CeLl-Porator and Voltage Booster were purchased from Bethesda Research Labs (Bethesda, MD~ . Protocols or competent cell preparation and ele.LL~.~ v, ltion are described in the I~struction manual. Transformants were selected on-LB agar plates supplemented with 50 ,~Lg~ml ampicillin.
3 5 Transformants were analyzed for harboring the correct recombinant plasmid using the alkaline lysis miniprep t~ hn;qr1c. (Molecular Cloning) . Miniprep DNA was analyzed by restriction enzyme mapping. 25 ml cultures of pRZ52 (CKB) and pRZ53 (C~¢) were grown in LB with 5011g/ml ampicillin and 40 larger scale DNA preps were purified using QIAGEN plasmid purification columns (QIAGEN Corp., Chatsworth, CA) .
Dideoxynucleoside chain-tF~rm;nAt;nn DNA secluencing reactions WO 95112662 ~ PC~IUS94112624 2~7~a were carried out according to the standard protocols described in the Sequenase 2 O kit from USB tCleveland, OH).
[-35S]-dATP (~ew ~ngland Nuclear~ was used to radiolabel the sequences for visualization on Kodak XAR film. Reactions 5 were separated through a 6% polyacrylamide gel, the gel dried, and expbsed to ilm as described in Molecular Cloning. The DNA sequence representing the coding regions of CKs and CKM are in ~igure G1 and 2.
Once the CKM DNA sequence was ~lPtPrmin~9 to be 10 correct the a~npicillin resistance gene in pRZ53 was exchanged for the kanamycin resistance gene from Tn903 ~Nomura et al., ~ene, 3:39-51, 1987). The ampicillin gene was cut out using the restriction enzymes Ssp~ and spml, and the vector ends were blunt ended using T4 polymerase. The 15 kanamycin resistance gene had been cloned into the polylinker in a pBR322 :vector. The gene was cut out of the vector using BamH1 and was blunt ended with T4 polymerase.
The resulting C~M plasmid is referred to as pRZ69.
20 t`orc:truct; n~ the CRMl~ Co-P~ression Strain pRZ52 and pRZ69 DNA was mixed together in a concentration o~ approximately 50 llg/ml and 1 1ll of the mixture electroporated into 20 1ll MClû61 cells. The cells were plated onto 1~3 plates containing 50 llg/ml ampicillin 25 and 50 llg/ml kanamycin to select or cells that had been co-tra~sformed with both plasmids. Co-transformants were analyzed ~y restriction digestion of miniprep DNA (the standard tP~ n; q~P is described in Molecular Cloning) .
WO 95112662 ~ 1 7 5 5 9 0 pC~ S94/12624 p\nA 1 vr i n F~-~nressinn Expression analysis of the co-transformants was carried out as follows. Clones were grown overnight in 2 ml LB, 0.2~s glucose, 50 llg/ml kanamycin and 50 llg/ml S i ~71l;n at 37 C shaking. In the morning 25 ml of LB with 50 ~Lg/ml kanamycin and 50 llg/ml ampicillin was inoculated with 0 . 6 ml of the overnight culture and grown at 30 C
shaking. Cultures were grown to A600 about 0.4 then sampled at one hour intervals for 4 hours. Cultures were left 10 growing overnight and an additional sample taken. Whole cell samples were boiled in SDS-PAGE sample buffer and run through 12% polyacrylamide gels to assess protein production Gels were obtained f rom BioRad, and protocols provided with gels were followed.
Several assays were used to ~F.t~rmin~ the level and quality of the expressed r~ mhinAnt proteir,. Cultures were grown as previously described. At A600 approximately 1. 0 or af ter overnight incubation cells were harvested and resuspended in a lysis buffer (20 mM Bis-Tris pH 6.9, 0.259 20 Tween 20, 10 mM b ~ptoethanol, 10 mM EDTA, 10 mM EGTA, lmM PNSF). The resuspended cells were lysed by sonication on ice (or for larger scale analysis cells were lysed using the Microfl~ ;7~r from Microfluidics Corp., Newton, MA ) and the cell debris removed by centrifugation. Samples were 2 5 analyzed using the following assay systems after diluting into lysis buffer. The Creatine Kinase Reagent (Sigma 47-UV) is a spectrophotometric assay for kinetic determination of enzyme activity. The Creatine Phosphokinase (CPK) Isoenzymes Kit (Sigma 715-EP) separates 3 0 the various isoforms (NM, MB, and BB) and stains for activity. The CR-MB assay system for the Abbott ~c analyzer uses a microparticle enzyme i oAqsay (MEIA) to determine specific protein mass of CR-MB in a sample. (A11 protocols are provided with the assay kits.

The GeneAmp PCR Reagent ~it with AmpliTaq DNA
Polymerase from Perkin Elmer Cetus (Norwalk, CT) was used for PCR reactions. The reactions were carried out following 2 5 standard procedures outlined in the literature enclosed in the kit Specifically, 5-30 ng DNA, 100 pmol primer DNA, 2.5 U AmpliTaq DNA polvmerase, and 200 ,umol dATP, dCTP, dGTP, dTTP were mixed with supplied buffer, and the reaction mix was overlayed with Ampliwax ( Perkin Elmer Cetus ) . The 3 0 PCR machine (Coy Laboratory Products, Inc . Grass Lake, MI) was ~L yL -d for ~ cycle of 94-C Lmelt) for 2 minutes, 55 C (anneal) for 2 minutes, 72 C (extend~ for 2 minutes, this cycle was repeated 1~3 times. A final extension step was run for 10 minutes to allow for complete polymerization 3 5 of all strands. PCR product (approximately 5-10 llg~ was digested with Ndel and EcoR1 ~for CKB~ or Ndel and BamH1 ~ for CKM) and purified by electrophoresis through a 0.7% low melting point agarose TAE buffered gel (FMC BioProducts, Inc. Rockland, ME~ for cloning into expression vectors.
40 Electrophoresis was performed as described in Molecular Cloning (Sambrook, Fritsch and M~n;~ti c, 198g. Cold Spring Harbor Press, Cold Spring Har~or, NY) . Restriction WO 95112662 217 rj S ~l ~ PC~IUS94/12624 endonucleases were purchased from New England BioLabs (Beverly, MA) and digestion reactions set up as suggested by the manufacturer. DNA fragments were purified from gel slices using the f.~nf~ An kit (BiolO1, La Jolla, CA~.
s Conqtruct;n~ thf~ S;~n - ~rnreccinn Vector r-R7~8 The expression vector was constructed at Genzyme as a derivative of the plasmid pBluescript SK +/-~available from Stratagene, La Jolla, CA). Expression is 10 driven off the Lac promoter. Our vector, pRZ38, was constructed by adding an restriction enzyme site at the ATG
start codon of the b-galactosidase gene through site-directed mutagenesis. Mutagenesis protocols were followed as described using the Muta-Gene In Vitro 15 Mutagenesis Rit from BioRad (Ri rl 1 , CA) . This change in the vector allows cloning of foreign genes after the LacZ
promoter but maintains similar spacing from the promoter as in the native gene.
20 ('lnn;n~t CKM ein~ CKR nN!~ ;nt~ R7~8 Vector DNA (5 llg) was digested with Ndel and EcoR1 (for CKB) or Ndel and BamH1 (for CKM~ and gel purified as above. Approximately 100 ng digested vector DNA and 100 ng digested PCR product were ligated in a 20 111 reaction (T4 25 DNA ligase purchased from NEB, Beverly, MA) . Ligation reactions set up as described in Molecular Cloning. After overnight ;n llh~t;nn at 15 C ligation mixes were diluted to 60~1 with dlI20. 1111 of each was electroporated into electroporation competent E. coli strain MC1061. The 3 0 CeLl-Porator and Voltage Booster were purchased from Bethesda Research Labs (Bethesda, MD~ . Protocols or competent cell preparation and ele.LL~.~ v, ltion are described in the I~struction manual. Transformants were selected on-LB agar plates supplemented with 50 ,~Lg~ml ampicillin.
3 5 Transformants were analyzed for harboring the correct recombinant plasmid using the alkaline lysis miniprep t~ hn;qr1c. (Molecular Cloning) . Miniprep DNA was analyzed by restriction enzyme mapping. 25 ml cultures of pRZ52 (CKB) and pRZ53 (C~¢) were grown in LB with 5011g/ml ampicillin and 40 larger scale DNA preps were purified using QIAGEN plasmid purification columns (QIAGEN Corp., Chatsworth, CA) .
Dideoxynucleoside chain-tF~rm;nAt;nn DNA secluencing reactions WO 95112662 ~ PC~IUS94112624 2~7~a were carried out according to the standard protocols described in the Sequenase 2 O kit from USB tCleveland, OH).
[-35S]-dATP (~ew ~ngland Nuclear~ was used to radiolabel the sequences for visualization on Kodak XAR film. Reactions 5 were separated through a 6% polyacrylamide gel, the gel dried, and expbsed to ilm as described in Molecular Cloning. The DNA sequence representing the coding regions of CKs and CKM are in ~igure G1 and 2.
Once the CKM DNA sequence was ~lPtPrmin~9 to be 10 correct the a~npicillin resistance gene in pRZ53 was exchanged for the kanamycin resistance gene from Tn903 ~Nomura et al., ~ene, 3:39-51, 1987). The ampicillin gene was cut out using the restriction enzymes Ssp~ and spml, and the vector ends were blunt ended using T4 polymerase. The 15 kanamycin resistance gene had been cloned into the polylinker in a pBR322 :vector. The gene was cut out of the vector using BamH1 and was blunt ended with T4 polymerase.
The resulting C~M plasmid is referred to as pRZ69.
20 t`orc:truct; n~ the CRMl~ Co-P~ression Strain pRZ52 and pRZ69 DNA was mixed together in a concentration o~ approximately 50 llg/ml and 1 1ll of the mixture electroporated into 20 1ll MClû61 cells. The cells were plated onto 1~3 plates containing 50 llg/ml ampicillin 25 and 50 llg/ml kanamycin to select or cells that had been co-tra~sformed with both plasmids. Co-transformants were analyzed ~y restriction digestion of miniprep DNA (the standard tP~ n; q~P is described in Molecular Cloning) .
WO 95112662 ~ 1 7 5 5 9 0 pC~ S94/12624 p\nA 1 vr i n F~-~nressinn Expression analysis of the co-transformants was carried out as follows. Clones were grown overnight in 2 ml LB, 0.2~s glucose, 50 llg/ml kanamycin and 50 llg/ml S i ~71l;n at 37 C shaking. In the morning 25 ml of LB with 50 ~Lg/ml kanamycin and 50 llg/ml ampicillin was inoculated with 0 . 6 ml of the overnight culture and grown at 30 C
shaking. Cultures were grown to A600 about 0.4 then sampled at one hour intervals for 4 hours. Cultures were left 10 growing overnight and an additional sample taken. Whole cell samples were boiled in SDS-PAGE sample buffer and run through 12% polyacrylamide gels to assess protein production Gels were obtained f rom BioRad, and protocols provided with gels were followed.
Several assays were used to ~F.t~rmin~ the level and quality of the expressed r~ mhinAnt proteir,. Cultures were grown as previously described. At A600 approximately 1. 0 or af ter overnight incubation cells were harvested and resuspended in a lysis buffer (20 mM Bis-Tris pH 6.9, 0.259 20 Tween 20, 10 mM b ~ptoethanol, 10 mM EDTA, 10 mM EGTA, lmM PNSF). The resuspended cells were lysed by sonication on ice (or for larger scale analysis cells were lysed using the Microfl~ ;7~r from Microfluidics Corp., Newton, MA ) and the cell debris removed by centrifugation. Samples were 2 5 analyzed using the following assay systems after diluting into lysis buffer. The Creatine Kinase Reagent (Sigma 47-UV) is a spectrophotometric assay for kinetic determination of enzyme activity. The Creatine Phosphokinase (CPK) Isoenzymes Kit (Sigma 715-EP) separates 3 0 the various isoforms (NM, MB, and BB) and stains for activity. The CR-MB assay system for the Abbott ~c analyzer uses a microparticle enzyme i oAqsay (MEIA) to determine specific protein mass of CR-MB in a sample. (A11 protocols are provided with the assay kits.
