Extreme cold sensitivity of Salmonella typhimurium umu clones, effects of the umu region and flanking sequences.

Mutation research - 1 Jan 1993

Thomas S M

Abstract excerpt

The umuDC operons of both Salmonella typhimurium and Escherichia coli encode proteins which are essential for mutagenesis following exposure to ultraviolet radiation or a variety of chemicals. However S. typhimurium is less mutable and its umu operon appears to be less active for reasons that are unknown. This study shows that pBR322-based plasmids carrying cloned umuDC operons of either species confer cold...
