Inactivation of protein translocation by cold-sensitive mutations in the yajC-secDF operon.
Most mutations in the yajC-secDF operon identified via genetic screens confer a cold-sensitive growth phenotype. Here we report that two of these mutations confer this cold-sensitive phenotype by inactivating the SecDF-YajC complex in protein translocation.
