WebThe proline hydroxylase that is involved in collagen maturation is well known, but in recent times many new enzymes and functions have been uncovered, including those involved in epigenetic control and hypoxia-inducible factor (HIF) regulation. These discoveries have provided crucial mechanistic insights into how ascorbate may affect tumor biology. WebThe enzymes proline hydroxylase and lysyl hydroxylase are important in the formation of the protein collagen. Hydroxylase means that the enzymes add alcohol (hydroxyl, -OH) to the amino acids proline and lysine, as shown below. Figure 9.321 Proline hydroxylase adds an alcohol group (circled) to proline forming hydroxyproline1,2
