Role of gene fadR in Escherichia coli acetate metabolism.

abstract：:We have previously cloned the genes for synthesis of capsular polysaccharide (cps) and slime from Erwinia stewartii in cosmid pES2144. In this study, pES2144 was shown to complement 14 spontaneous cps mutants. These mutants were characterized by probing Southern blots of mutant genomic DNA with pES2144; insertions wer...

abstract：:Nisin is a cationic antimicrobial peptide that belongs to the group of lantibiotics. It is thought to form oligomeric pores in the target membrane by a mechanism that requires the transmembrane electrical potential delta psi and that involves local pertubation of the lipid bilayer structure. Here we show that nisin do...
