Abstract excerpt
Escherichia coli delta prc mutants lacking periplasmic protease Prc, which was originally found involved in the C-terminal processing of penicillin-binding protein (PBP) 3, show thermosensitive growth at low osmolarity. We isolated thermoresistant revertants containing extragenic suppressor (spr) mutations. In the prc+ background the mutations also caused thermosensitivity at low osmolarity. They were all mapped...
