Användbara är emellertid även i ß-ställning stående substi-
tuenter. I sistnämnda fall användes dessutom förutom OC-gluko-
sidas jämväl ß-glukosidas.
Vid dinitrofenylrester kan de båda nitrogrupperna förefin-
nas i godtycklig ställning, exempelvis som 2,4-, 2,6- eller
3,5-substituenter.
De vid avspjälkningen av nitrogrupper innehållande substi-
tuenter frigjorda nitrofenolerna resp. dinitrofenolerna är själva
färgade föreningar, som utan vidare kan bestämmas optískt. Av-
spjälkas fenol som sådan, sä kan denna bestämmas enligt kända
metoder, exempelvis genom omsättning med ett nukleofílt reagens,
såsom 3-metyl-6-sulfonyl-benstiazolon-hydrazon-(2) (HSK) i när-
varo av monofenoloxidas. Vid denna reaktion bildas ett rött
färgämne, som kan mätas. De för detta ändamål använda malto-
heptaosderivaten framställes enligt uppfinningen genom ett för-
farande, som kännetecknas därav, att fenylglukosid resp. nítrerad
fenylglukosid bringas att reagera med M-cyklodextrin i närvaro
av Bacillus macerans amylas E.C.2.4.1.19. I den enligt uppfin-
ningen genomförda.transglukosideringen användes den kända amylasen
från Bacillus macerans [E.C. 2.4.1.19. DSM 24; isolering: J.A.
de Pinto, L.L. Cambell, Biochemistry 1, 114 (1968); Transfer-
reaction: Methods in Carbohydr. Chemistry, vol II, 3471].
Följande exempel åskådliggör uppfinningen._
Exempel
p-nítrofenyl- - maltooligosackarid genom enzymatisk
syntes med Bac. maeerans-amylas
(E.C.2.4.1.19 ur Bac. macerans DSM 24)
Bacillus macerans-amylas har förutom hydrolytisk och cyk-
liserande verkan även glukosyl-transfererande egenskaper, vilka
kan användas för syntes av olígosackarider och -derivat (Methods
in Carbohydrate Chemistry II, 347). För syntesen av p-nitro-
fenyl-oligosackarider optimerades detta förfarande på följande
sätt:
680 mg Bacillus macerans-amylas (E.C.2.4.1.19 ur Bac.
macerans DSM 24) Clyofilisat) (0,46 U/mg invägning, proteinhalt
av invägningen 28,5%, fri från p-nitrofenyl- -D-glukosid-spjä1-
kande aktiviteter),
400 mg 0eD-p-nitrofenylglukosid,
3,5 g oecyklodextrin, och
70 ml Sörensen-fosfatbuffert, pH 6,2; 0,01 M blandades.
3 454 ss?
.p
Satsen ínkuberades 24 h vid 37°C. För rening separerades därpå
ol- och bildad ß-cyklodextrin närmast över tetrakloretylen-ínne-
slutningsföreníng. Efter kromatografi medelst tvärbindningsbun-
det dextrans ("Sephadex LI-I20") erhölls 50 mg lyofílísat av i amy-
lastest högaktiv p-nítrofenyl-maltoheptaosid.
