Protein synthesis results in guanosine-5'-diphosphate-3'-diphosphate synthesis in Escherichia coli minicells

Abstract

Minicells of Escherichia coli DS410 synthesized guanosine-5'-diphosphate-3'-diphosphate and guanosine-5'-triphosphate-3'-diphosphate when synthesizing proteins in response to phage T7 infection. The guanosine-5'-diphosphate-3'-diphosphate synthesis was found to be relA+ dependent and inhibited by chloramphenicol.
