A PF01979 Amidohydro_1 Amidohydrolase family Domain This family of enzymes are a a large metal dependent hydrolase superfamily [1]. The family includes Adenine deaminase EC: that hydrolyses adenine to form hypoxanthine and ammonia. Adenine deaminases reaction is important for adenine utilisation as a purine and also as a nitrogen source [2]. This family also includes dihydroorotase and N-acetylglucosamine-6-phosphate deacetylases, EC: These enzymes catalyse the reaction N-acetyl-D-glucosamine 6-phosphate + H2O <=> D-glucosamine 6-phosphate + acetate. This family includes the catalytic domain of urease alpha subunit [3]. Dihydroorotases (EC: are also included [4-5]. PFAM PF01979
