1 Apparent involvement of purines in the control of expression of Salmonella typhimurium pyr genes: analysis of a leaky guaB mutant resistant to pyrimidine analogs. pyrimidine IMP dehydrogenase Salmonella enterica subsp. enterica serovar Typhimurium str. LT2
2 A leaky guaB mutant of Salmonella typhimurium LT-2 was obtained during a selection for mutants resistant to a combination of the two pyrimidine analogs, 5-fluorouracil and 5-fluorouridine. pyrimidine IMP dehydrogenase Salmonella enterica subsp. enterica serovar Typhimurium str. LT2
3 The pyrimidine metabolism of the guaB mutant is restored completely by addition of guanine (or xanthine) to the growth medium. pyrimidine IMP dehydrogenase Salmonella enterica subsp. enterica serovar Typhimurium str. LT2
