General annotation (Comments)

Function

Catalyzes the post-translational formation of 4-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins.

Catalytic activity

Procollagen L-proline + 2-oxoglutarate + O2 = procollagen trans-4-hydroxy-L-proline + succinate + CO2.

Cofactor

Binds 1 Fe2+ ion per subunit.

Ascorbate.

Enzyme regulation

In contrast to the subunit alpha-1, alpha-2 is inhibited by poly(L-proline) only at very high concentrations.

Subunit structure

Heterotetramer of two alpha-2 chains and two beta chains (the beta chain is the multi-functional PDI).

Subcellular location

Endoplasmic reticulum lumen.

Tissue specificity

Expressed in a variety of tissues.

Sequence similarities

Belongs to the P4HA family.

Contains 1 PKHD (prolyl/lysyl hydroxylase) domain.

Contains 1 TPR repeat.
