The function of this domain is not known, but it is thought to be involved in riboflavin biosynthesis. This domain is found in the C terminus of RibD/RibG Swiss:P25539, in combination with Pfam:PF00383, as well as in isolation in some archaebacterial proteins Swiss:P95872. This family appears to be related to Pfam:PF00186.	Domain
