查询词典 crystal diffraction

Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR,EC 1.1.1.50 ) from Comamonas testosteroni is an inducible enzyme which catalyzes the oxidation of androsterone with NAD+ to form androstanedione and NADH. 3α-HSD/CR was a member of the SDRs family, whose crystal structure had been solved by X-ray diffraction in 2000. The structure of 3α-HSD/CR is a homodimer which shows a typical pattern of Rossmann-fold structure consisting of βαβ units, and reaveals similarity with other members upon the SDRs family.

中文摘要 3α-Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR，EC 1.1.1.50 )是从Comamonas testosteroni菌体中分离而来的诱发性酵素，利用NAD+为辅因子，将受质androsterone氧化成androstanedione并伴随NADH的生成而完成催化反应。3α-HSD/CR是属於SDRs家族成员之一，其立体结构已经在2000年利用X-ray晶体绕射所解出。3α-HSD/CR在结构上为一同源双聚体，并和其它家族成员一样具有βαβ二级结构所叠合组成的Rossmann-fold特徵。
