We have examined a polymorphism for liver GOX in inbred strains of the mouse Mus musculus. Genetic studies demonstrated that the two phenotypes for this enzyme present in BALB/C and NZC parental strains segregated as though they were controlled by codominant alleles at a single autosomal locus (GOX) which mapped closely to the agouti locus in linkage group V. Kidney HAOX activity is invariant in these inbred strains and is encoded by a separate genetic locus designated HAOX. BALB/C x NZC F(1) hybrid mice exhibited three intermediate forms of liver GOX activity, in addition to the parental enzymes, which is consistent with a tetrameric subunit structure.
我们研究了小家鼠近交系中肝脏GOX的多态性。遗传学研究表明,BALB/C和NZC亲本品系中该酶的两种表型的分离方式,就好像它们是由位于常染色体上一个单一基因座(GOX)的共显性等位基因所控制,该基因座与第五连锁群中的刺鼠基因座紧密连锁。在这些近交系中,肾脏HAOX活性不变,且由一个单独的基因座HAOX编码。BALB/C×NZC F(1)杂种小鼠除了具有亲本酶之外,还表现出三种肝脏GOX活性的中间形式,这与四聚体亚基结构一致。
