[Regulation of purine biosynthetic genes expression in Salmonella typhimurium. II. Isolation and characterization of Oc mutants].

Yi chuan xue bao = Acta genetica Sinica - 1 Jan 1993

Abstract excerpt

Purine repressor protein, encoded by purR has shown to effect expression of purine structure genes except purB in de novo pathway in Salmonella typhimurium. However, up to date there is no direct evidence of the repressor binding to operator DNA of these genes. Report here is the isolation and characterization of purine Oc mutants in Salmonella typhimurium. purD:: MudJ (lacZ Kanr) and purG:: MudJ (lacZ Kanr) were...
