1. Requirement of autolytic activity for bacteriocin-induced lysis

Author

Martinez-Cuesta, M. Carmen, Kok, Jan, Herranz, Elisabet, Pelaez, Carmen, Requena, Teresa, and Buist, Girbe

Subjects
Bacterial toxins -- Research, Biological sciences
Abstract

Autolysins appear to be responsible for lysis induced by bacteriocin produced by Lactococcus lactis. Autolysins are peptidoglycan hydrolases that can lyse bacterial cells.

2. Heterologous production of methionine-[gamma]-lyase from Brevibacterium linens in Lactococcus lactis and formation of volatile sulfur compounds

Abstract

The bioengineering of food-grade L. lactis strains to synthesize methionine-[gamma]-lyase (MGL) which plays a significant role in the catabolism of Met to MTL in Brevibacterium linens, a good producer of volatile sulfur compounds (VSCs) is described. The lactic acid bacteria with enhanced VSC-producing abilities could find potential use to enhance cheese flavor development.

3. YtjE from Lactococcus lactis IL1403 is a C-S lyase with alpha, gama-elimination activity toward methionine

Abstract

YtjE, a putative methionine-specific aminotransferase is characterized and its participation in methionine catabolism is elucidated and also, its role in volatile sulfur compounds (VSCs) production was investigated. Cloning and expressing the YtjE gene isolated from Lactococcus lactis IL1403 in Escheriachia coli was performed and the YtjE recombinant protein was purified and characterized.
