A PF00699 Urease_beta Urease beta subunit Domain This subunit is known as alpha in Heliobacter. PFAM PF00699
B PF00449 Urease_alpha Urease alpha-subunit, N-terminal domain Domain The N-terminal domain is a composite domain and plays a major trimer stabilising role by contacting the catalytic domain of the symmetry related alpha-subunit. PFAM PF00449
B 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
A PF00547 Urease_gamma Urease, gamma subunit Domain Urease is a nickel-binding enzyme that catalyses the hydrolysis of urea to carbon dioxide and ammonia. PFAM PF00547
