IUBMB Enzyme Nomenclature

EC 3.5.4.37

Accepted name: double-stranded RNA adenine deaminase

Reaction: adenine in double-stranded RNA + H2O = hypoxanthine in double-stranded RNA + NH3

Other name(s): ADAR; double-stranded RNA adenosine deaminase; dsRAD; dsRNA adenosine deaminase; DRADA1; double-stranded RNA-specific adenosine deaminase

Systematic name: double-stranded RNA adenine aminohydrolase

Comments: This eukaryotic enzyme is involved in RNA editing. It destabilizes double-stranded RNA through conversion of adenosine to inosine. Inositol hexakisphosphate is required for activity [4].
