Abstract
ABSTRACT
We investigated the regulation of the
psbA
and
pvdA
pyoverdine biosynthesis genes, which encode the
l
-ornithine
N
5
-oxygenase homologues in
Pseudomonas
strain B10 and
Pseudomonas aeruginosa
PAO1, respectively. We demonstrate that pyoverdine
B10
, as the end product of its biosynthetic pathway, is a key participant of the control circuit regulating its own production in
Pseudomonas
strain B10. In
P. aeruginosa
PAO1, however, pyoverdine
PAO1
has no apparent role in the positive regulation of the
pvdA
gene.
