The secD locus of E.coli codes for two membrane proteins required for protein export.

The EMBO journal - 1 Oct 1990

Gardel C, Johnson K, Jacq A, Beckwith J

Abstract excerpt

Cold-sensitive mutations in the secD locus of Escherichia coli result in severe defects in protein export at the non-permissive temperature of 23 degrees C. DNA sequence of a cloned fragment that includes the secD locus reveals open reading frames for seven polypeptide chains. Both deletions and TnphoA insertions in this clone have been used in maxicell and complementation studies to define the secD locus and its...
