Abstract
The traG protein of the F sex factor is an inner membrane protein with a molecular weight of 116,000. Mutants in traG (or in traN) are able to trigger conjugal DNA replication even though they cannot efficiently form stable mating aggregates with F(-) cells. The traG protein (and the traN protein) probably acts in the donor at the stabilization stage of conjugation.
摘要
F 性因子的 traG 蛋白是一种分子量为 116,000 的内膜蛋白。traG（或 traN）突变体能够引发接合 DNA 复制，尽管它们不能有效地与 F(-)细胞形成稳定的交配聚集体。traG 蛋白（和 traN 蛋白）可能在供体中接合的稳定阶段发挥作用。
