Moonlighting role of a poly-gamma-glutamate synthetase component from Bacillus subtilis: insight into novel extrachromosomal DNA maintenance.

ABSTRACT: The Bacillus subtilis structural gene pgsE was investigated as a tool for extrachromosomal DNA maintenance (EDM). It ameliorated the stability of high-copy-number vectors, regardless of whether they were derived from rolling-cycle or theta-mode replicons, without any selective pressure. This unique EDM phenomenon may occur via a trans-acting mechanism.
