Degradation of thymidine by Lactobacillus acidophilus.

abstract：:Bacterial pathogenesis depends on changes in metabolic and virulence gene expression in response to changes within a pathogen's environment. The plague-causing pathogen, Yersinia pestis, requires expression of the gene encoding the Pla protease for progression of pneumonic plague. The catabolite repressor protein Crp,...
