Aspartyl/Asparaginyl beta-hydroxylase
Iron (II)/2-oxoglutarate (2-OG)-dependent oxygenases catalyze oxidative reactions in a range of metabolic processes. Proline 3-hydroxylase hydroxylates proline at position 3, the first of a 2-OG oxygenase catalysing oxidation of a free alpha-amino acid. The structure of proline 3-hydroxylase contains the conserved motifs present in other 2-OG oxygenases including a jelly roll strand core and residues binding iron and 2-oxoglutarate, consistent with divergent evolution within the extended family. This family represent the arginine, asparagine and proline hydroxylases. The aspartyl/asparaginyl beta-hydroxylase (EC:1.14.11.16) specifically hydroxylates one aspartic or asparagine residue in certain epidermal growth factor-like domains of a number of proteins.
