guaA and guaB mutants of Salmonella typhimurium were isolated utilizing the mutagen, nitrous acid. The guaB mutants were defective for inosine 5'-monophosphate (IMP) dehydrogenase activity and those mutants classified as guaA exhibited no xanthosine 5'-monophosphate aminase activity. In vivo complementation maps were determined for the mutants. The guaB map indicated that at least three complementation regions existed whereas five complementation regions were observed for the guaA mutants. The… CONTINUE READING
