Disulfide bond formation in alkaline phosphatase
and OmpA in wild-type, dsbC−,
dsbA−, and
dsbA−/dsbC−
strains. Pulse-chase experiments were performed as described. The
positions of reduced and oxidized alkaline phosphatase and OmpA are
indicated. The strains used were RI89 (wild type), RI179
(ΔdsbC::cam), RI90
(dsbA::kan1), and RI181
(ΔdsbC::cam
dsbA::kan1).
