tRNA-specific adenosine deaminase 2 isoform X1 [Homo sapiens]

Protein Classification

nucleoside deaminase( domain architecture ID 10001752)

nucleoside deaminase such as adenosine, guanine, or cytosine deaminase is a Zn-dependent enzyme which catalyzes the deamination of nucleosides. The zinc ion in the active site plays a central role in the proposed catalytic mechanism, activating a water molecule to form a hydroxide ion that performs a nucleophilic attack on the substrate. The functional enzyme is a homodimer

 72-178 1.35e-36

Nucleoside deaminases include adenosine, guanine and cytosine deaminases. These enzymes are Zn dependent and catalyze the deamination of nucleosides. The zinc ion in the active site plays a central role in the proposed catalytic mechanism, activating a water molecule to form a hydroxide ion that performs a nucleophilic attack on the substrate. The functional enzyme is a homodimer. Cytosine deaminase catalyzes the deamination of cytosine to uracil and ammonia and is a member of the pyrimidine salvage pathway. Cytosine deaminase is found in bacteria and fungi but is not present in mammals; for this reason, the enzyme is currently of interest for antimicrobial drug design and gene therapy applications against tumors. Some members of this family are tRNA-specific adenosine deaminases that generate inosine at the first position of their anticodon (position 34) of specific tRNAs; this modification is thought to enlarge the codon recognition capacity during protein synthesis. Other members of the family are guanine deaminases which deaminate guanine to xanthine as part of the utilization of guanine as a nitrogen source.

 82-165 5.12e-05

Riboflavin-specific deaminase. Riboflavin biosynthesis protein RibD (Diaminohydroxyphosphoribosylaminopyrimidine deaminase) catalyzes the deamination of 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate, which is an intermediate step in the biosynthesis of riboflavin.The ribG gene of Bacillus subtilis and the ribD gene of E. coli are bifunctional and contain this deaminase domain and a reductase domain which catalyzes the subsequent reduction of the ribosyl side chain.

 83-163 1.54e-04

Deoxycytidylate deaminase domain. Deoxycytidylate deaminase catalyzes the deamination of dCMP to dUMP, providing the nucleotide substrate for thymidylate synthase. The enzyme binds Zn++, which is required for catalytic activity. The activity of the enzyme is allosterically regulated by the ratio of dCTP to dTTP not only in eukaryotic cells but also in T-even phage-infected Escherichia coli, with dCTP acting as an activator and dTTP as an inhibitor.

Cytidine and deoxycytidylate deaminase zinc-binding region. The family contains cytidine deaminases, nucleoside deaminases, deoxycytidylate deaminases and riboflavin deaminases. Also included are the apoBec family of mRNA editing enzymes. All members are Zn dependent. The zinc ion in the active site plays a central role in the proposed catalytic mechanism, activating a water molecule to form a hydroxide ion that performs a nucleophilic attack on the substrate.

Bd3614-like deaminase; A member of the nucleic acid/nucleotide deaminase superfamily prototyped by Bdellovibrio Bd3614. They are typified by a distinct N-terminal globular domain. The Bdellovibrio version occurs in a predicted operon with a 23S rRNA G2445-modifying methylase suggesting that it might be involved in RNA editing.
