Activating Compound

Activating Compound Comment Organism Structure
additional information protein disulfide-isomerase is able to activate the purified enzyme, the activation is probably due to the repairing of disulfide exchanges ocurring in the prolyl 4-hydroxylase structure during purification and storage. Protein disulfide-isomerase is also able to reactivate the enzyme inactivated by mild H2O2 treatment Gallus gallus

Inhibitors

Inhibitors Comment Organism Structure
dithiothreitol 95-100% inhibition at 0.45 mM Gallus gallus
H2O2 94% inhibition at 1 M, dissociation of the enzyme, 12% of the enzyme remains in the tetrameric form Gallus gallus

Renatured (Commentary)

Renatured (Comment) Organism
protein disulfide-isomerase may be an enzyme that is able to retain the prolyl 4-hydroxylase structure in its native conformation, but it seems to lack the ability to associate the enzyme monomers into the active tetrameric form Gallus gallus
