Abstract
The ppsR gene (R. J. Penfold and J. M. Pemberton, J. Bacteriol. 176:28 69-2876, 1994) from Rhodobacter sphaeroides 2.4.1 functions as a trans criptional repressor of puc and bchF expression. The carboxy terminus of PpsR, containing the putative DNA-binding domain, by itself possess es repressor activity. Intact palindromes having the motif TGT-N-12-AC A are required for PpsR activity.
