Methylenediurea deaminase

Template:Infobox enzyme Methylenediurea deaminase (Template:EC number, methylenediurease) is an enzyme with systematic name methylenediurea aminohydrolase found in Brucella anthropi, a bacterium. This enzyme catalyses the following chemical reaction:

methylenediurea + 2 H₂O $\rightleftharpoons$ N-(hydroxymethyl)urea + 2 NH₃ + CO₂ (overall reaction)

(1a) methylenediurea + H₂O $\rightleftharpoons$ N-(carboxyaminomethyl)urea + NH₃

(1b) N-(carboxyaminomethyl)urea $\rightleftharpoons$ N-(aminomethyl)urea + CO₂ (spontaneous)

(1c) N-(aminomethyl)urea + H₂O $\rightleftharpoons$ N-(hydroxymethyl)urea + NH₃ (spontaneous)

Methylenediurea is hydrolysed and decarboxylated to give an aminated methylurea.
