>TIGR00734 hisAF_rel hisA/hisF family protein; InterPro: IPR004650 This family of proteins has so far been found in three archaeal species: Methanobacterium thermoautotrophicum, Methanococcus jannaschii, and Archaeoglobus fulgidus. Proteins are homologous to phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (HisA) and, with lower similarity, to the cyclase HisF, both of which are enzymes of histidine biosynthesis. Each species with this protein also encodes HisA. However, the function of proteins in this group is unknown..
