IUBMB Enzyme Nomenclature


Accepted name: protein-serine epimerase

Reaction: [protein]-L-serine = [protein]-D-serine

Other name(s): protein-serine racemase

Systematic name: [protein]-serine epimerase

Comments: the enzyme specifically interconverts the configuration of Ser-46 of the peptide ω-agatoxin-KT, found in the venom of the funnel web spider, Agelenopsis aperta, but not that of the other serine residue, Ser-28.
