Molecular cloning and analysis of the ptsHI operon in Lactobacillus sake.

Applied and environmental microbiology - 1 Jun 1997

Stentz R, Lauret R, Ehrlich S D, Morel-Deville F, Zagorec M

Abstract excerpt

The ptsH and ptsI genes of Lactobacillus sake, encoding the general enzymes of the phosphoenolpyruvate: carbohydrate phosphotransferase system (PTS), were cloned and sequenced. HPr (88 amino acids), encoded by ptsH, and enzyme I (574 amino acids), encoded by ptsI, are homologous to the corresponding known enzymes of other bacteria. Nucleotide sequence and mRNA analysis showed that the two genes are cotranscribed...
