Regulation of ptsH and ptsI gene expression in Streptococcus salivarius ATCC 25975.

Molecular microbiology - 1 Jun 1995

Gagnon G, Vadeboncoeur C, Gauthier L, Frenette M

Abstract excerpt

The transcriptional regulation of the Streptococcus salivarius ptsH and ptsI genes coding for the general energy-coupling proteins HPr and enzyme I of the phosphoenolpyruvate:sugar phosphotransferase system were investigated. These genes form an operon with the gene order ptsH-ptsI. Three distinct mRNA species were detected: a 0.5 kb transcript specific for ptsH, and two long transcripts (2.2 and 2.4 kb) covering...
