Sysname
tRNA(cytosine8) aminohydrolase
Reaction(IUBMB)
cytosine8 in tRNA + H2O = uracil8 in tRNA + NH3 [RN:
R10232 ]
Reaction(KEGG)
Substrate
cytosine8 in tRNA;

Comment
The enzyme from Methanopyrus kandleri specifically catalyses the deamination 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.
