Reaction: KDM8:Fe2+ hydroxylates an arginine residue of RPS6
- in pathway: Protein hydroxylation
KDM8 (JMJC5 - JmjC domain-containing protein 45), active when bound to Fe2+, catalyzes the hydroxylation of an arginine residue of the ribosomal protein RPS6 (40S small ribosomal protein 6). The subcellular location of this reaction under physiological conditions has not been determined; it is arbitrarily annotated as cytosolic.
KDM8, a member of the JmjC protein family, was originally assigned to the branch of the family that catalyzes histone lysine demethylation reactions. Structural studies have shown a closer resemblance to the protein hydroxylation branch of the family (Del Rizzo et al. 2012; Wang et al. 2013), a suggestion confirmed by in vitro studies with synthetic peptides (Wilkins et al. 2018). These studies identified RPS6 as a likely hydroxylation target.
