The Mystery of Vitamin C In 1962, through analysis of the radioactivity incorporated into collagen using a tritiated version of the amino acid proline, Stone and Meister discovered that vitamin C is used as a co-substrate by peptidyl-prolyl hydroxylase, an enzyme that catalyzes the selective modification of proline to hydroxyproline.onsequently, the lack of vitamin C results in the formation of non-functional collagen in blood vessels and bones, which accounts for most of the severe bone and blood vessel related symptoms.

Cyclic guanosine monophosphate Guanylate cyclase (GC) catalyzes cGMP synthesis. This enzyme converts GTP to cGMP. Peptide hormones such as the atrial natriuretic factor activate membrane-bound GC, while soluble GC (sGC) is typically activated by nitric oxide to stimulate cGMP synthesis. sGC can be inhibited by ODQ (1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one).

The GULO Pseudogene and Its Implications for Common Descent Jonathan M. L-gulonolactone oxidase (GULO), the final enzyme in the biosynthetic pathway of ascorbic acid (vitamin C), is a subject that comes up often in discussions of common ancestry. The functioning GULO gene allows most plants and many animals to produce vitamin C from glucose or galactose.n some taxa, however, the GULO gene does not function in this capacity and is given the pseudogene label. The GULO gene is thought to be broken in humans (Nishikimi and Yagi, 1991), primates and guinea pigs (Nishikimi et al., 1994; Nishikimi et al., 1988), as well as in bats of the genus Pteropus (Cui et al., 2011).

Protease The structure of a protease (TEV protease) complexed with its peptide substrate in black with catalytic residues in red. (PDB: 1LVB​) A protease (also called a peptidase or proteinase) is any enzyme that performs proteolysis; protein catabolism by hydrolysis of peptide bonds. Proteases have evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms.

What Enzyme Catalyzes DNA Synthesis? Quick Answer. DNA polymerases is the enzyme that catalyzes DNA synthesis, but it is different from RNA polymerases. This particular type of polymerases have specific conditions and requirements that must be met for them to be produced. Without these enzymes, the nucleotides that are the building blocks of DNA cannot be made.

Vitamin C and Skin Health Specifically, vitamin C has been shown to stabilize collagen mRNA, thus increasing collagen protein synthesis for repair of the damaged skin (47) . This occurs concurrently with a decrease in elastin production; the elastin protein is often overproduced in response to photodamage (48) .n addition to its antioxidant functions, vitamin C regulates the synthesis of the structural protein collagen. The role of vitamin C in the hydroxylation of collagen molecules is well characterized (46) . Hydroxylation of collagen is necessary for its extracellular stability and support of the epidermis.

Collagen Metabolism 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).
