(10aS)-5,10-dihydrophenazine-1-carboxylate
Comment
Requires FMN. The enzyme, isolated from the bacteria Pseudomonas fluorescens 2-79 and Burkholderia lata 383, is involved in biosynthesis of the reduced forms of phenazine, phenazine-1-carboxylate, and phenazine-1,6-dicarboxylate, where it catalyses multiple reactions.
