>TIGR00673 cynS cyanate hydratase; InterPro: IPR008076 Cyanase, an enzyme found in bacteria and plants, catalyses the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide, allowing the host organisms to overcome the toxicity of environmental cyanate . The cyanate lyase monomer is composed of two domains: an N-terminal domain that shows structural similarity to the DNA-binding alpha-helix bundle motif, and a C-terminal domain that has an 'open fold' that shows no structural similarity to other proteins . The enzyme is active as a homodecamer of 17kDa subunits, and displays half-site binding of substrates or substrate analogues. The dimer structure reveals the C-terminal domains to be intertwined; the decamer is formed from a pentamer of these dimers. The active site of the enzyme is located between dimers and comprises residues from four adjacent subunits of the homodecamer. Synonym(s): cyanase lyase, cyanase hydrolase ; GO: 0016836 hydro-lyase activity, 0008152 metabolic process.
