Chromopyrrolic acid is a pyrroledicarboxylic acid that is pyrrole-2,5-dicarboxylic acid in which the hydrogens at positions 3 and 4 have been replaced by indol-3-yl groups. It has a role as a bacterial metabolite. It is a member of indoles and a pyrroledicarboxylic acid. WebDichlorochromopyrrolate synthase ( EC 1.21.3.9, RebD, dichlorochromopyrrolic acid synthase) is an enzyme with systematic name 2-imino-3- (7-chloroindol-3-yl)propanoate ammonia-lyase (dichlorochromopyrrolate-forming).
