Abstract

Catenated deoxyribonucleic acid molecules of colicin factor E1 (Col E1) were found with nearly equal frequency in minicells derived from Escherichia coli strain P678-54 recA(+) (Col E1) and P678-54 recA(-) (Col E1). The result suggests that the recombination function controlled by the recA gene does not influence the formation of catenated Col E1.

摘要

在源自大肠杆菌菌株P678 - 54 recA(+)（Col E1）和P678 - 54 recA(-)（Col E1）的微小细胞中，发现了连环的大肠杆菌素E1因子（Col E1）脱氧核糖核酸分子，其出现频率几乎相等。该结果表明，由recA基因控制的重组功能并不影响连环Col E1的形成。
