Key:

PfamA domain

Secondary structure



		Enzyme reactions

Enzyme class 2:

E.C.4.2.1.1 - carbonic anhydrase.

[IntEnz] [ExPASy] [KEGG] [BRENDA]

Reaction:

hydrogencarbonate + H⁺ = CO2 + H2O

hydrogencarbonate	+	H(+)	=	CO2	+	H2O

Cofactor:

Zn(2+)

Enzyme class 3:

E.C.4.2.1.69 - cyanamide hydratase.

[IntEnz] [ExPASy] [KEGG] [BRENDA]

Reaction:

urea = cyanamide + H2O

urea	=	cyanamide	+	H2O

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
