Survey on proteolytic activity and diversity of proteinase genes in mesophilic lactobacilli
Abstract
Lactocepins or CEPs are large cell wall bound extracellular proteinases of lactic acid bacteria, involved in protein breakdown and utilization. They are responsible for many health-promoting traits of food products fermented with these organisms, but also essential for probiotic effects of certain strains. Different mesophilic strains selected within the species Lactobacillus zeae, Lb. casei, Lb. rhamnosus, and Lb. plantarum were analyzed for their proteolytic activity towards main fractions of milk proteins-caseins and whey proteins. The strains showing excellent proteolytic features were further examined for presence of corresponding proteinase gene(s). It was found that Lb. zeae LMG17315 possessed catalytic domains of three distinct proteinase genes, unique feature in Lb. casei group, which are similar but not identical to previously characterized prtP and prtR genes. Lb. casei neotype strain ATCC393 was also analysed and based on obtained results its reclassification in taxon Lb. z...eae is supported. In addition, we report catalytic domain of prtR-type gene in Lb. plantarum LMG9208, which is first such report in this species, and it is first time that this gene is reported outside Lb. casei group.
