Type: | Domain | Name: | Phosphoribosyl-AMP cyclohydrolase domain |
Description: | Phosphoribosyl-AMP cyclohydrolase catalyses the third step in the histidine biosynthetic pathway: 5-phosphoribosyl-AMP + H2O = 5-(5-phospho-D-ribosylaminoformimino)-1-(5-phospho-ribosyl) imidazole-4-carboxamide It requires Zn2+ions for activity []. | Short Name: | PRib_AMP_CycHydrolase_dom |
