Specific enzymes called hydroxylases are responsible for these important reactions needed to form hydroxyproline and hydroxylysine. The hydroxylase enzymes require Vitamin C and Iron as cofactors. If a patient is Vitamin C deficient, then this reaction will not occur.n the extracellular spaces, another post-translational modification takes place as the triple helical collagen molecules (Figure 1) line up and begin to form fibrils and then fibers. This step is called crosslink formation and is promoted by another specialized enzyme called lysyl oxidase (Figure 3).
