Characterization of degQ and degS, Escherichia coli genes encoding homologs of the DegP protease.

Journal of bacteriology - 1 Feb 1996

Waller P R, Sauer R T

Abstract excerpt

The degQ and degS genes of Escherichia coli encode proteins of 455 and 355 residues, respectively, which are homologs of the DegP protease. The purified DegQ protein has the properties of a serine endoprotease and is processed by the removal of a 27-residue amino-terminal signal sequence. A plasmid expressing degQ rescues the temperature-sensitive phenotype of a strain bearing the degP41 deletion, implying that...
