Allantoate hydrolysis by allantoate amidohydrolase
Archives of Biochemistry and Biophysics, 1970Abstract The degradation of allantoate by allantoate amidohydrolase from Streptococcus allantoicus resulted in the production of 1 mole of carbon dioxide, 2 moles of NH 3 , and probably 1 mole of (−)-ureidoglycolate per mole of allantoate. Ureidoglycine was an intermediate and presumably also a substrate for allantoate amidohydrolase.

Dihydropyrimidine amidohydrolase is a zinc metalloenzyme
Biochimica et Biophysica Acta (BBA) - Enzymology, 1979Bovine liver dihydropyrimidine amidohydrolase (EC 3.5.2.2) has been subjected to atomic absorption analysis. Three different preparations of homogeneous enzyme indicated that the enzyme contains 4.3 +/- 0.3 g atoms of Zn2+ per mol of enzyme or 1.1 g atoms of Zn2+ per subunit. No Co2+, Mn2+, Mg2+ or Cd2+ was detected.

Journal of Molecular Biology, 2014
In plants, the ureide pathway is a metabolic route that converts the ring nitrogen atoms of purine into ammonia via sequential enzymatic reactions, playing an important role in nitrogen recovery. In the final step of the pathway, (S)-ureidoglycolate amidohydrolase (UAH) catalyzes the conversion of (S)-ureidoglycolate into glyoxylate and releases two ...

The characterization of amidohydrolases in a freshwater lake sediment
Microbial Ecology, 1989The properties of three amidohydrolases, i.e., urease (I) EC 3.5.1.5, L-asparaginase (II) EC 3.5.1.1, and L-glutaminase (III) EC 3.5.1.2, were studied in sediment samples taken from a shallow eutrophic freshwater lake.Sediment samples were air dried (ADS) and stored for at least 3 months before being enzymically characterized.

The Purification and Properties of an Amidohydrolase from Soybean
Canadian Journal of Biochemistry, 1974An amidohydrolase (EC 3.5.1.13) was isolated from the roots of soybean (Glycine max Merril, var. Hawkeye) seedlings and purified 130-fold over the crude extract with 30% recovery. The purification steps entailed ammonium sulfate precipitation, gel filtration, cellulose ion-exchange chromatography, and polyacrylamide gel electrophoresis.

Glutaminase activity of L-asparagine amidohydrolase
Biochemical Pharmacology, 1969Relatively high concentrations of 6-diazo-5-oxo-norleucine (DON) and azaserine, potent specific inhibitors of many enzymes using glutamine as substrate, do not have an appreciable effect on the activity of Escherechia coliL-asparagine amido-hydrolase (EC 3.5.1.1) when either asparagine or glutamine is used as substrate.

Mechanism and thermodynamics of ligand binding to auxin amidohydrolase
Journal of Molecular Recognition, 2011AbstractBrILL2 is catalytically the most efficient auxin amidohydrolase from Brassica rapa, playing a key role in auxin metabolism by catalyzing its release from amino acid conjugates. Auxins, with the most abundant representative indole‐acetic acid ([1H‐indol‐3‐yl]‐acetic acid, IAA), are a group of plant hormones that in very small concentrations ...
