Description
Technical field
The present invention relates to a kind of preparation method and pharmaceutical composition thereof of enzyme, be specifically related to a kind of preparation method and pharmaceutical composition thereof of natural arginine esterase.Belong to the biological medicine technology field.
Background technology
Snake venom thrombin-like enzyme be in the snake venom with the general name of the class of enzymes of blood plasma zymoplasm similar performance, have the arginine ester enzymic activity usually, be called arginine esterase again.But fine proteinogen in its enzymolysis blood, but do not swash in vivo various thrombin.Therefore can make blood plasma or fibrin solution solidifies external, and the fibrin clotted texture that generates in vivo is loose, is easily removed by fibrinolytic system, and fine proteinogen concentration is significantly descended, and shows anticoagulation.This specific character makes arginine esterase become the important source of developing the thrombolytic-anticoagulant medicine, but there is multiple non-synonym coding mutation in arginine esterase molecular gene inside, and the isozyme of arginine esterase be there are differences on function.Contain arginine esterase isozyme more than 4 kinds in the viper venom, transformation period, Substratspezifitaet, specific activity are all had any different in the molecular weight of enzyme, degree of glycosylation, the body.Therefore as the clinical treatment medicine time, need separate, carry out structural confirmation, measure that amino acid is formed, the-terminal amino acid sequence, and accurately measure data such as relative molecular weight.Separation not exclusively can cause and contain multiple other echidnotoxin in the arginine esterase finished product, side reaction may occur in clinical application; The restive aborning quality product of product that while protein structure and character are fully identified can not ensure the security that medicine uses, harm patient life and health.Therefore, need development snake venom arginine esterase new preparation technology, and the arginine esterase of preparation is carried out sufficient structure and character evaluation, the security in the time of could ensureing as medicine.
Find through literature search prior art, Zhai Ning etc. have delivered the paper that is entitled as " a kind of separation and purification of new Thrombin-like enzyme in the ahylysantinfarctase " at " Chinese Journal of Pharmaceuticals " (2005 36 volume 601-603 pages or leaves), following technical scheme is proposed: at first use the anion-exchange chromatography preliminary purification, secondly make with extra care with high-efficient gel filtration chromatography, use the Thrombin-like enzyme purity of high-efficient gel filtration chromatography analyte preparation at last.Because this method uses gel filtration chromatography as one of preparation means, therefore exist applied sample amount low, yield poorly, shortcoming that production efficiency is difficult to improve.Simultaneously, because this research is not carried out sufficient protein structure and character evaluation to the Thrombin-like enzyme of preparation, be difficult to as curative drug.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of preparation method and pharmaceutical composition thereof of natural arginine esterase are provided, make it can quick, easy preparation natural arginine esterase, and preparation contains the pharmaceutical composition of this natural arginine esterase, is used for the treatment of and prevents multiple thrombus and embolism class diseases.

Embodiment 3 measures the natural arginine esterase molecular mass
Get the natural arginine esterase highly finished product and mix, put about 1 μ l on target with sinapinic acid matrix, after the seasoning, the mass spectrograph of packing into (Brukerg company produces, model AutoFlex MALDI-TOF-TOF-MS), N
2Laser source (wavelength 337nm); Detect (flight pipe range 1.22M with the positive ion linear mode, acceleration voltage 20KV), obtain MALDI-TOP MS collection of illustrative plates, there is mass peak at m/z 17503,34069,68138, be respectively half point protonatomic mass, molecular mass and two times of molecular masses, so the natural arginine esterase molecular mass is 34.07 ± 0.20kDa.
Measure natural arginine esterase molecule sugar degree
It is freezing dry to get natural arginine esterase highly finished product solution (52 μ g/ml) desalination, add 20 μ l trifluoromethanesulfonic acids (TFMS),-70 ℃ of reactions are spent the night, the acetonitrile 1200 μ l that add-20 ℃ of precoolings then, mixing, under 12000rpm, 4 ℃ of conditions, acetonitrile and TFMS are removed in centrifugal 35min ultrafiltration with centrifugal ultrafiltration pipe (YM-10); Repeat once to add precooling acetonitrile-ultrafiltration again and remove acetonitrile and trifluoromethanesulfonic acid, add 600 μ l ultrapure waters at last again, mix, centrifugal ultrafiltration, remove residual acetonitrile and trifluoromethanesulfonic acid, collect last solution and find in electrophorogram, to occur altogether apparent molecular weight 36.3,34.9,33.8,30.4kDa totally 4 bands with the analysis of SDS-polyacrylamide gel electrophoresis, wherein 36.3,34.9,33.8kDa three bands content about 10% altogether, band 30.4kDa content is about 85%, is speculated as the agkistrodon acutus natural arginine esterase goods of complete desugar chain.Reclaim the albumen of band 30.4kDa, mix, put about 1 μ l on target with sinapinic acid matrix, after the seasoning, the mass spectrograph of packing into (Brukerg company produces, model AutoFlex MALDI-TOF-TOF-MS), N
2Laser source (wavelength 337nm) detects (flight pipe range 1.22M, acceleration voltage 20KV) with the positive ion linear mode, obtain mass-spectrogram, having a mass peak at m/z 28007 places, is the molecular mass after the natural arginine esterase desugar, is 28.01 ± 0.20kDa.Therefore sugar degree is that the complete molecular mass of natural arginine esterase deducts and is molecular mass 34.07-28.01 behind the desugar chain, and sugar degree is about 6.06 ± 0.20kDa.
Measure 15 aminoacid sequences of N end
Get the band 30.4kDa of the SDS-polyacrylamide gel electrophoresis of desugar natural arginine esterase, changeing the film system with half dry type albumen goes to albumen on polyvinylidene difluoride (PVDF) (PVDF) film, utilize the method for Edman degraded, measure the sequence of amino-acid residue from polypeptide chain free N-terminal, the N-terminal amino-acid residue is modified by PhNCS, downcut the residue of modifying from polypeptide chain then, identify through HPLC (high performance liquid chromatography) that again continuously tested has obtained preceding 17 round-robin amino acid high performance liquid chromatography and identified collection of illustrative plates.15 aminoacid sequences of N end are:
Val?Ile?Gly?Gly?Val?Glu?Cys?Asp?Ile?Asn?Glu?His?Arg?Phe?Leu
The pH stability test of natural arginine esterase
Getting natural arginine esterase highly finished product 40 μ l, to add 600 μ l pH respectively be 4,5,6 0.1M sodium-acetate buffer, pH is that 7,8 40mM Tris-HCl damping fluid and pH are in the Gly-NaOH damping fluid of 9,10,11,12 10nm, mix in back and 37 ℃ of water-baths and hatch a week, in 12% each sample of reduction SDS-PAGE electrophoretic analysis.Electrophoresis result shows that under pH 4,5,6 conditions, the natural arginine esterase of purifies and separates is that 40.3 ± 0.2KD place exists unique protein band at apparent molecular weight; Under pH 7,8 and 9 conditions, sample is that 40.3 ± 0.2KD and about 28.1 ± 0.2KD place exist two protein bands at apparent molecular weight; Under pH 10,11,12 conditions, almost do not seen at apparent molecular weight being the protein band at 40.3 ± 0.2KD place in the sample, all degradeds are described almost.Therefore, this natural arginine esterase is more stable under pH 4,5,6 conditions, keeps pH 4-6 as far as possible in production and storage process.
