Abstract

Electrophoretic polymorphisms for stomach alcohol dehydrogenase (ADH-C2) and kidney L-alpha-hydroxyacid oxidase (HAOX-B4) have been identified in an Asian subspecies of mouse, Musmusculus castaneous. These variants are inherited in a normal Mendelian fashion with two alleles in each case showing codominant expression. The structural gene loci for those enzymes (Adh-3 and Hao-2, respectively) are apparently linked (17.6% recombinants) in this organism, whereas the multiple gene loci for HAOX, Hao-1 (encoding the A4 liver isozyme) and Hao-2, exhibited independent segregation and are unlinked (50% recombinants). Evidence is presented for 3 ADH loci: ADH-1, encoding liver ADH-A2 which exhibits high activity with ethanol (SELANDER, HUNT and YANG 1969; ADH-2, liver and stomach ADH-B2 using 2-hexene-1-ol as substrate; and Adh-3, stomach ADH-C2 using both benzyl alcohol and 2-hexene-1-ol as substrate.

摘要

在小家鼠亚洲亚种(M. castaneous)中已鉴定出胃醇脱氢酶(ADH-C2)和肾L-α-羟基酸氧化酶(HAOX-B4)的电泳多态性。这些变体以正常孟德尔方式遗传,每种情况下的两个等位基因均表现为共显性表达。在该生物体中,这些酶的结构基因座(分别为Adh-3和Hao-2)显然是连锁的(重组率为17.6%),而HAOX的多个基因座,即Hao-1(编码A4肝脏同工酶)和Hao-2,表现出独立分离且不连锁(重组率为50%)。文中提供了3个ADH基因座的证据:ADH-1,编码肝脏ADH-A2,对乙醇具有高活性(SELANDER、HUNT和YANG,1969年);ADH-2,肝脏和胃中的ADH-B2,以2-己烯-1-醇为底物;以及Adh-3,胃中的ADH-C2,以苯甲醇和2-己烯-1-醇为底物。
