This domain is found in diverse flavoprotein enzymes, including covering the whole length of the sequence of epidermin biosynthesis protein from Staphylococcus epidermidis (EpiD, Swiss:P30197), which has been shown to bind FMN [1]. This enzyme catalyses the removal of two reducing equivalents from the cysteine residue of the C-terminal meso-lanthionine of epidermin to form a --C==C-- double bond. This family also includes the B chain of dipicolinate synthase a small polar molecule that accumulates to high concentrations in bacterial endospores, and is thought to play a role in spore heat resistance, or the maintenance of heat resistance [2]. dipicolinate synthase catalyses the formation of dipicolinic acid from dihydroxydipicolinic acid. This family also includes phenyl-acrylic acid decarboxylase Swiss:P33751 (EC:4.1.1.-) [3].	Domain

A	phosphopantothenoylcysteine decarboxylase M-CSA #639	The Arabidopsis thaliana flavoprotein AtHAL3a catalyses the oxidative decarboxylation of 4'-phosphopantothenoylcysteine to 4'-phosphopantetheine, a step in coenzyme A biosynthesis. It belongs to the family of homo-oligomeric flavin-containing cysteine decarboxylases (HFCD) family.
