We have isolated uracil auxotrophic mutants of an extreme thermophile, Thermus thermophilus. A part of the pyrimidine biosynthetic operon including genes for orotate phosphoribosyltransferase (pyrE) and for orotidine-5'-monophosphate decarboxylase (pyrF) was cloned and sequenced. The pyrE gene can be a bidirectional marker for the gene manipulation system of the thermophile.
我们已经分离出嗜热栖热菌(Thermus thermophilus)这种极端嗜热菌的尿嘧啶营养缺陷型突变体。克隆并测序了嘧啶生物合成操纵子的一部分,包括乳清酸磷酸核糖转移酶(pyrE)基因和乳清苷-5'-单磷酸脱羧酶(pyrF)基因。pyrE基因可以作为嗜热菌基因操作系统的双向标记。
