Evidence for the presence of an endogenous inhibitor of prolyl hydroxylase
Date of Original Version
Prolyl hydroxylase [EC 220.127.116.11] was shown to be inhibited by an ultrafiltrate (less than 30,000 molecular weight) fraction isolated from skin and blood of neonatal and adult rabbits. This fraction also inhibited two other α-ketoglutarate requiring mixed function oxidases, lysyl hydroxylase [EC 18.104.22.168] and α-butyrobetaine hydroxylase [EC 22.214.171.124] but not the amine oxidase, lysyl oxidase. Purification of the skin ultrafiltrate on Sephadex G-25 demonstrated a peak of prolyl hydroxylase inhibitory activity which chromatographed at a molecular weight corresponding to approximately 3,000. Chromatography of a blood ultrafiltrate separated a similar peak of material which was inhibitory for prolyl hydroxylase.
