Abstract
Spontaneous crp mutants Escherichia coli were selected from a strain that does not require 3',5'-cyclic adenosine monophosphate for CAP activity. Several deletions of the crp gene were characterized. The crp gene was not essential for growth of E. coli. crp mutations reduced the donor ability of Hfr strains.
摘要
从一株对CAP活性不需要3',5'-环磷酸腺苷的菌株中筛选出自发的crp突变型大肠杆菌。对crp基因的几个缺失进行了表征。crp基因对大肠杆菌的生长不是必需的。crp突变降低了Hfr菌株的供体能力。
