Cyanate lyase (also known as cyanase) EC:4.2.1.104 is responsible for the hydrolysis of cyanate, allowing organisms that possess the enzyme to overcome the toxicity of environmental cyanate. This enzyme is composed of two domains, an N-terminal helix-turn-helix and this structurally unique C-terminal domain [2].	Domain
