Two diacetyl reducing enzymes have been isolated from beef liver. One of them, a monomer of mol. wt 28-30,000 dalton and pI 6.2, corresponds to the low molecular weight diacetyl reductase formerly accounted for using preparations of this organ; it has been now identified as an L-glycol dehydrogenase. The other one, an oligomer of 78,000 dalton and pI 7.0, which matches the high molecular weight diacetyl reductase, is, in the authors' opinion, a new enzyme for which the systematic name L(+)-alpha-hydroxycarbonyl: NAD(P) oxidoreductase (EC 1.1.1...) and common name alpha-dicarbonyl reductase are proposed.
已从牛肝中分离出两种二乙酰还原酶。其中一种是分子量为28 - 30,000道尔顿、等电点为6.2的单体，它与以前用该器官的制剂所描述的低分子量二乙酰还原酶相对应；现已确定它是一种L - 二醇脱氢酶。另一种是分子量为78,000道尔顿、等电点为7.0的寡聚体，它与高分子量二乙酰还原酶相符，作者认为它是一种新酶，为此提出其系统名称为L(+)-α - 羟基羰基:NAD(P)氧化还原酶(EC 1.1.1...)，通用名称为α - 二羰基还原酶。
