KEGG   ENZYME: 1.4.99.5Help
Entry
EC 1.4.99.5                 Enzyme                                 

Name
glycine dehydrogenase (cyanide-forming);
hydrogen cyanide synthase;
HCN synthase
Class
Oxidoreductases;
Acting on the CH-NH2 group of donors;
With unknown physiological acceptors
BRITE hierarchy
Sysname
glycine:acceptor oxidoreductase (hydrogen-cyanide-forming)
Reaction(IUBMB)
glycine + 2 acceptor = hydrogen cyanide + CO2 + 2 reduced acceptor [RN:R05704]
Reaction(KEGG)
Substrate
glycine [CPD:C00037];
acceptor [CPD:C00028]
Product
hydrogen cyanide [CPD:C01326];
CO2 [CPD:C00011];
reduced acceptor [CPD:C00030]
Comment
The enzyme from Pseudomonas sp. contains FAD. The enzyme is membrane-bound, and the 2-electron acceptor is a component of the respiratory chain. The enzyme can act with various artificial electron acceptors, including phenazine methosulfate.
