The soil bacterium Bacillus subtilis has developed a highly controlled system for the
utilization of a diverse array of low-molecular-weight compounds as a nitrogen source when …

ABSTRACT The PucR protein of Bacillus subtilis has previously been suggested to regulate
the expression of 15 genes, pucABCDE, pucFG, pucH, pucI, pucJKLM, pucR, and gde, all of …

Expression of the P3 promoter of the Bacillus subtilis ureABC operon is activated during
nitrogen-limited growth by PucR, the transcriptional regulator of the purine-degradative …

In Bacillus subtilis expression of genes or operons encoding enzymes and other proteins
involved in purine synthesis is affected by purine bases and nucleosides in the growth …

The expression of the pur operon, which encodes enzymes of the purine biosynthetic
pathway in Bacillus subtilis, is subject to control by the purR gene product (PurR) and …

In Bacillus subtilis, the expression of genes encoding enzymes and other proteins involved
in purine de novo synthesis and salvage is affected by purine bases and …

The genes encoding the enzymes of IMP biosynthesis in Bacillus subtilis constitute the pur
operon, whereas the genes encoding GMP biosynthetic enzymes, guaA (GMP synthetase) …

Regulation of the purine biosynthetic gene purA was examined by using a transcriptional
fusion to a luciferase reporter gene. Transcription was repressed about 10-fold by the …

Bacillus subtilis PurR represses transcription of several genes involved in purine synthesis,
metabolism, and transport and cofactor synthesis. PurR binds specifically to DNAs …

The first complete purine nucleotide formed in the purine biosynthetic pathway is IMP, which
is converted to AMP and GMP via two separate pathways. The pathways by which purine …
