EC 1.3.8.14

Accepted name: L-prolyl-S-[peptidyl-carrier protein] dehydrogenase

Reaction: S-(L-prolyl)-[peptidyl-carrier protein] + 2 electron-transfer flavoprotein = S-(1H-pyrrole-2-carbonyl)-[peptidyl-carrier protein] + 2 reduced electron-transfer flavoprotein

Other name(s): pigA (gene name); bmp3 (gene name); pltE (gene name); redW (gene name)

Systematic name: S-(L-prolyl)-[peptidyl-carrier protein]:electron-transfer flavoprotein oxidoreductase

Comments: 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)-S-[peptidyl-carrier protein] intermediate, followed by a two-electron oxidation to 1H-pyrrol-2-yl(carbonyl)-S-[peptidyl-carrier protein].
