Abstract

A mutation, previously designated lex-113 and suspected to be situated in the lexA locus, has been positioned by transductional studies to a unique site on the chromosome of E. coli B separate from the lexA102 and uvrA155 mutations. The order of genes in this chromosomal region was demonstrated to be malB-lexA-uvr A-lex-113. The allele designation lexC-113 is suggested for this mutation in a new gene functional in the regulation of inducible lex ⁺ - and rec ⁺ — dependent SOS activities.
