Lactobacillus helveticus: the proteolytic system
Lactobacillus helveticus is one of the species of lactic acid bacteria (LAB) most commonly used in the production of fermented milk beverages and some types of hard cheese. The versatile nature of this bacterium is based on its highly efficient proteolytic system consisting of cell-envelope proteinases (CEPs), transport system and intracellular peptidases. Besides use of L. helveticus in cheese...

2 Department of Food Science, University of Wisconsi nMad ison, WI 53706, USA A prolinase (pepR) gene was cloned from an industrial Lactobacillus helveticus strain (53/7). Three clones, hybridizing with a gene probe specific for a peptidase shown to have activity against diand tripeptides, were detected from a L. helveticus genomic library constructed in Escherichia coli. None of the three clon...

متن کاملA Novel Branched Chain Amino Acids Responsive Transcriptional Regulator, BCARR, Negatively Acts on the Proteolytic System in Lactobacillus helveticus
Transcriptional negative regulation of the proteolytic system of Lactobacillus helveticus CM4 in response to amino acids seems to be very important for the control of antihypertensive peptide production; however, it remains poorly understood. A 26-kDa protein with N-terminal cystathionine β-synthase domains (CBS domain protein), which seems to be involved in the regulatory system, was purified ...
متن کاملHealth-Promoting Properties of Lactobacillus helveticus
Lactobacillus helveticus is an important industrial thermophilic starter that is predominantly employed in the fermentation of milk for the manufacture of several cheeses. In addition to its technological importance, a growing body of scientific evidence shows that strains belonging to the L. helveticus species have health-promoting properties. In this review, we synthesize the results of numer...
