HIS4 , hisIE and hisD genes. Schematic representation of the archaeal, bacterial and eukaryotic genes coding for phosphoribosyl-ATP pyrophosphohydrolase (hisI), phosphoribosyl-AMP cyclohydrolase (hisE) and histidinol dehydrogenase (hisD). The HisI and HisE proteins are coded by a bifunctional gene or two separate cistrons in both Archaea and Bacteria and by a bifunctional gene in all Eukarya. Homologus regions are represented by the same hatching.
