摘要：

A series of isogenic strains harboring known deletions in the pts operon of Escherichia coli have been constructed by reverse genetics. Strains bearing deletions for the whole pts operon failed to grow on maltose or on carbon sources of the same class. In these strains the total cAMP synthesis was significantly lower than in a strain deleted only for the crr gene. This indicated that enzyme I or phosphorylated histidine-containing phosphotransferase protein in addition to its role in phosphorylating enzyme IIIGlc, is involved in adenylate cyclase (AC) activation or cAMP excretion. It was further shown that deletions in the pts operon do not affect synthesis of AC. © 1990.
