SecA protein: autoregulated initiator of secretory precursor protein translocation across the E. coli plasma membrane.

Abstract excerpt

Several classes of secA mutants have been isolated which reveal the essential role of this gene product for E. coli cell envelope protein secretion. SecA-dependent, in vitro protein translocation systems have been utilized to show that SecA is an essential, plasma membrane-associated, protein translocation factor, and that SecA's ATPase activity appears to play an essential but as yet undefined role in this...
