IUBMB Enzyme Nomenclature

EC 3.5.4.35

Accepted name: tRNA(cytosine8) deaminase

Reaction: cytosine8 in tRNA + H2O = uracil8 in tRNA + NH3

Other name(s): CDAT8

Systematic name: tRNA(cytosine8) aminohydrolase

Comments: The enzyme from Methanopyrus kandleri specifically catalyses the deamimation of cytosine at position 8 of tRNA in 30 different tRNAs. This cytosine-to-uracil editing guarantees the proper folding and functionality of the tRNAs.
