Abstract:
secDF mutants of Flavobacterium johnsoniae were deficient in gliding motility and chitin utilization. Cells of the mutants had reduced levels of GldJ protein, which is required for both processes. SecDF is similar to Escherichia coli SecD and SecF, which are involved in protein secretion.
