Shikimate Dehydrogenase - Function

Function

Shikimate dehydrogenase is an enzyme that catalyzes one step of the shikimate pathway. This pathway is found in bacteria, plants, fungi, algae, and parasites and is responsible for the biosynthesis of aromatic amino acids (phenylalanine, tyrosine, and tryptophan) from the metabolism of carbohydrates. In contrast, animals and humans lack this pathway hence products of this biosynthetic route are essential amino acids that must be obtained through an animal's diet.

There are seven enzymes that play a role in this pathway. Shikimate dehydrogenase (also known as 3-dehydroshikimate dehydrogenase) is the fourth step of the seven step process. This step converts 3-dehydroshikimate to shikimate as well as reduces NADP+ to NADPH.

Famous quotes containing the word function:

    Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
    Susanne K. Langer (1895–1985)

    Every boy was supposed to come into the world equipped with a father whose prime function was to be our father and show us how to be men. He can escape us, but we can never escape him. Present or absent, dead or alive, real or imagined, our father is the main man in our masculinity.
    Frank Pittman (20th century)

    It is the function of vice to keep virtue within reasonable bounds.
    Samuel Butler (1835–1902)
