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.
