Transcription factor: PurR

Factor type	Purine biosynthesis
SWISS-PROT	P37551
SubtiList	BG10110
Consensus seq.	ANNNCGAA---22-23bp---ANNNTTCGNNNNT
Comment	a purine repressor which mediates adenine nucleotide-dependent regulation of pur operon. GAAC-N24-GTTC motif seems necessary for its binding but this motif was not required for its binding to purA
