[Elaboration of chloramphenicol acetyltransferase by cells of E. coli K-12 under conditions altering the intracellular concentration of cyclic adenosine-3',5'-monophosphate].
The influence of cAMP, ACTH and glucose on the stimulation of chloramphenicol acetyl transferase synthesis in the cells of E. coli CSH-2/R222 and E. coli WZ-78/R222. (cya855) was examined. Glucose proved to decrease the enzyme synthesis in E. coli CSH-2/R222, causing catabolite repression; 5 mM of cAMP and 1000 mug/ml ACTH overcame the latter. The enzyme synthesis in E. coli WZ-78/R222 was insensitive to the catabolite repression; as to ACTH - it failed to cause stimulation ofchloramphenicol acetyl transferase synthesis in E. coli WZ-78/R222.
