How Do You Spell PREPHENATE DEHYDRATASE?

Pronunciation: [pɹɪfˈɛne͡ɪt dˌiːha͡ɪdɹˈate͡ɪs] (IPA)

Prephenate Dehydratase is a biomolecule involved in the biosynthesis of the aromatic amino acids. The spelling of this word can be explained using the International Phonetic Alphabet (IPA). The first part of the word, "prephenate," is pronounced /priːˈfɛnət/ with the stress on the second syllable. "Dehydratase" is pronounced /diːˈhaɪdreɪteɪz/, with the stress on the third syllable. The word is commonly used in the field of biochemistry and is crucial in understanding the process of amino acid synthesis.

PREPHENATE DEHYDRATASE Meaning and Definition

1. Prephenate dehydratase is an enzyme that plays a crucial role in the metabolic pathway of the amino acid biosynthesis known as the shikimate pathway. More specifically, it catalyzes the conversion of prephenate, an intermediate compound, into phenylpyruvate. This conversion occurs through the elimination of water from prephenate, leading to the formation of double bonds within the molecule.

   Prephenate dehydratase is considered a key regulatory enzyme in the shikimate pathway because it catalyzes a branch point reaction. This means that it produces phenylpyruvate, which serves as a precursor for the synthesis of various aromatic amino acids such as phenylalanine, tyrosine, and tryptophan.

   The activity of prephenate dehydratase is tightly regulated in cells, as the production of aromatic amino acids is essential for protein synthesis and other vital cellular processes. Inhibition or malfunction of this enzyme can lead to disruptions in the biosynthesis of aromatic amino acids, affecting cellular growth and development.

   Similar to other dehydratase enzymes, prephenate dehydratase requires metal ions, such as magnesium or manganese, as cofactors for its activity. These cofactors assist in the enzymatic reaction mechanism by coordinating the substrates and stabilizing the transition state, ultimately promoting the dehydration process.

   In summary, prephenate dehydratase is an enzymatic catalyst involved in the shikimate pathway, facilitating the conversion of prephenate to phenylpyruvate by eliminating a water molecule. Its activity is crucial for the biosynthesis of aromatic amino acids, making it an important target for studying and modulating cellular metabolism.

Etymology of PREPHENATE DEHYDRATASE

The word "prephenate dehydratase" is derived from two separate components: "prephenate" and "dehydratase".

1. Prephenate: Prephenate is a compound found in the shikimate pathway, which is a metabolic pathway in plants, bacteria, and fungi that leads to the production of aromatic amino acids. The term "prephenate" ultimately comes from the combination of two words: "pre-" and "phenylalanine".

- "Pre-" is a prefix meaning "before" or "in advance".

- "Phenylalanine" is an essential amino acid found in proteins. Its name is formed from two components - "phenyl" (derived from "benzene ring") and "alanine" (an amino acid).
