Abstract excerpt
As an approach for studying how SecY, an integral membrane protein translocation factor of Escherichia coli, interacts with other protein molecules, we isolated a dominant negative mutation, secY-d1, of the gene carried on a plasmid. The mutant plasmid severely inhibited export of maltose-binding protein and less severely of OmpA, when introduced into sec+ cells. It inhibited growth of secY and secE mutant cells,...
