This family of enzymes are a a large metal dependent hydrolase superfamily [1]. The family includes Adenine deaminase EC:3.5.4.2 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:3.5.1.25 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:3.5.2.3) are also included [4-5]. [1]. 9144792.

amidohydrolase is a metal-dependent hydrolase such as 5-methylthioadenosine/S-adenosylhomocysteine deaminase, which catalyzes the deamination of 5-methylthioadenosine and S-adenosyl-L-homocysteine into 5-methylthioinosine and S-inosyl-L-homocysteine, respectively
