... three polypeptides, and hydroxylation of proline residues is vital for the stability of this triple-helix. Prolyl-4-hydroxylase (P4H) is an enzyme with an α2β2 tetramer arrangement that functions to post-translationally hydroxylate proline residues in the collagen chain. The α subunit (P4Hα) of the P4H α2β2 tetramer contains the catalytic site, whereas the β subunit (PDI) maintains the solubility and activity of the &alp...
