Accepted name:
L-prolyl-[peptidyl-carrier protein] dehydrogenase
Other names:
pigA (gene name)
bmp3 (gene name)
pltE (gene name)
redW (gene name)
Systematic name:
(L-prolyl)-[peptidyl-carrier protein]:electron-transfer flavoprotein oxidoreductase




Contains FAD. The enzyme participates in the biosynthesis of several pyrrole-containing compounds, such as undecylprodigiosin, prodigiosin, pyoluteorin, and coumermycin A1. It is believed to catalyse the formation of a Δ2-pyrrolin-2-yl(carbonyl)-[peptidyl-carrier protein] intermediate, followed by a two-electron oxidation to 1H-pyrrol-2-carbonyl-[peptidyl-carrier protein].
