The products from the enzymatic beta-D-galactopyranosylation of 1D-chiro-inositol, 1D-pinitol, 1D-3-O-allyl-4-O-methyl-chiro-inositol, 1D-3,4-di-O-methyl-chiro-inositol, 1L-chiro-inositol and myo-inositol in combined yields ranging from 46% to 64% have been obtained using the beta-galactosidase isolated from an anaerobic extreme thermophile, Thermoanaerobacter sp. strain TP6-B1 and p-nitrophenyl b
1D-手性肌醇,1D-松醇,1D-3-O-烯丙基-4-O-甲基-手性肌醇,1D-3,4-二-O-甲基的酶促β-D-吡喃半乳糖基化产物-β-手性肌醇,1L-手性肌醇和肌醇的总收率范围为46%至64%,这是使用从厌氧性嗜热嗜热菌嗜热厌氧菌(Thermoanaerobacter sp。)分离得到的β-半乳糖苷酶获得的。菌株TP6-B1和对硝基苯基β-D-吡喃半乳糖苷作为供体。这些反应产物的分析揭示了有关酶受体偏好的信息。
