Proteolysis by Lactobacillus casei
A study of the proteinase activity of Lactobacillus casei grown in milk and of cell-free extract of L. cawi has been reported on in a previous paper (Brandsaeter and Nelson, 1956). Whereas the proteinases of L. casei have been studied to some extent earlier, very little has been done to characterize the peptidases of this organism. Other lactobacilli hydrolyze some peptides (Christophersen and ...
متن کاملCharacterization of the Adaptive Amoxicillin Resistance of Lactobacillus casei Zhang by Proteomic Analysis
Amoxicillin is one of the most commonly prescribed antibiotics for bacterial infections and gastrointestinal disorders. To investigate the adaptation of Lactobacillus (L.) casei Zhang to amoxicillin stress, an iTRAQ-based comparative proteomic analysis was performed to compare the protein profiles between the parental L. casei Zhang and its amoxicillin-resistant descendent strains. Our results ...

متن کاملBacteriophage exclusion, a new defense system.
The ability to withstand viral predation is critical for survival of most microbes. Accordingly, a plethora of phage resistance systems has been identified in bacterial genomes (Labrie et al, 2010), including restriction‐modification systems (R‐M) (Tock & Dryden, 2005), abortive infection (Abi) (Chopin et al, 2005), Argonaute‐based interference (Swarts et al, 2014), as well as clustered regular...
متن کاملA novel nucleotide kinase encoded by gene 1.7 of bacteriophage T7.
Gene 1.7 of bacteriophage T7 confers sensitivity of both phage T7 and its host Escherichia coli to dideoxythymidine (ddT). We have purified the product of gene 1.7, gp1.7. It exists in two forms of molecular weight 22,181 and 17,782. Only the C-terminal half of the protein is required to confer ddT sensitivity. We show that gp1.7 catalyses the phosphorylation of dGMP and dTMP to dGDP and dTDP, ...
