The JmjC domain belongs to the Cupin superfamily [3]. JmjC-domain proteins may be protein hydroxylases that catalyse a novel histone modification [4]. This is confirmed to be a hydroxylase: the human JmjC protein named Tyw5p unexpectedly acts in the biosynthesis of a hypermodified nucleoside, hydroxy-wybutosine, in tRNA-Phe by catalysing hydroxylation [5].
