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。

The formation of martensite is accomplished by the immigration of well-defined glissile interface (121)fcc type and its misfit dislocations can produce the lattice invariant deformation on the basis of phenomenal theory of martensitic crystallography, however, LID is retarded slightly after the migration of interphase (121)fcc, i.e.a thin plate-like zone exists without LID in martensite near the well-defined interface. When the temperature reduces to the Ms point, the lattice parameter of austenite matrix is √3/2 times that of the martensite without LID. This critical condition for spontaneous transformation agrees with that the stack fault energy in matrix is less than zero according to Olson and Cohen's nucleation model.

通过模型分析表明：fcc/bcc马氏体形核与长大过程是通过(121)fcc型择优界面推移进行的，界面上的错配位错可以完成马氏体晶体学唯象理论要求的点阵不变变形，但LID要稍滞后于界面迁移，即在马氏体形核与长大过程中推移界面新相一侧存在一未发生LID的新相薄区；当相变温度达到马氏体相变点Ms时，母相奥氏体与这一薄区的晶格常数比为√3/2，这一几何条件和Olson-Cohen形核模型中要求扩展位错层错区界面能γ≤0是等价的。
