Abstract
A thermosensitive mutation pt8I1 in the gene coding for the Enzyme I of the PEP-phosphotransferase system pathway has been isolated. The mutant enzyme was shown to be sensitive to high temperature, but this effect is dependent on the ionic strength. The ptsI1 mutation was shown to belong to the previously described ctr locus. Following Lin (1970) it is proposed to retain the symbole ptsI for this locus.
摘要
已分离出一种编码磷酸烯醇式丙酮酸磷酸转移酶系统途径中酶 I 的基因的热敏突变体 pt8I1。该突变酶对高温敏感，但这种效应取决于离子强度。ptsI1 突变被证明属于先前描述的 ctr 位点。按照林（1970 年）的建议，保留该位点的符号 ptsI。
