Identification and overexpression in Escherichia coli of a Mycobacterium leprae gene, pon1, encoding a high-molecular-mass class A penicillin-binding protein, PBP1.

abstract：:The PhoQ/PhoP two-component system is repressed by divalent cations, such as Mg(2+) and Ca(2+), in the growth medium and stimulated by low pH and certain cationic antimicrobial peptides. In Escherichia coli, it was recently shown that the histidine kinase PhoQ is also modulated by at least two additional factors, the ...
