Bacillus subtilis guanine deaminase is encoded by the yknA gene and is induced during growth with purines as the nitrogen source.

Microbiology (Reading, England) - 1 Dec 2000

Abstract excerpt

Bacillus subtilis can utilize the purine bases adenine, hypoxanthine and xanthine as nitrogen sources. The utilization of guanine as a nitrogen source is reported here. The first step is the deamination of guanine to xanthine catalysed by guanine deaminase (GDEase). To isolate mutants defective in GDEase activity, a collection of mutant strains was screened for strains unable to use guanine as a nitrogen source....
