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

Cyanate hydratase (also known as cyanate lyase) catalyses the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide, allowing the host organisms to overcome the toxicity of environmental cyanate [1-4]. It consists of an N-terminal five-helix bundle domain that shows structural similarity to DNA-binding HTH domains and a C-terminal catalytic domain, which has a unique fold [4].	Domain
