IUBMB Enzyme Nomenclature


Accepted name: [50S ribosomal protein L16]-arginine 3-hydroxylase

Reaction: [50S ribosomal protein L16]-L-Arg81 + 2-oxoglutarate + O2 = [50S ribosomal protein L16]-(3R)-3-hydroxy-L-Arg81 + succinate + CO2

Other name(s): ycfD (gene name)

Systematic name: [50S ribosomal protein L16]-L-Arg81,2-oxoglutarate:oxygen oxidoreductase (3R-hydroxylating)

Comments: The enzyme, characterized from the bacterium Escherichia coli, hydroxylates an arginine residue on the 50S ribosomal protein L16, and is involved in regulation of bacterial ribosome assembly.
