Molybdopterin biosynthesis翻译
WebSummary The biosynthesis of the molybdenum cofactor (Moco) is highly conserved among all kingdoms of life. In all molybdoenzymes containing Moco, the molybdenum atom is coordinated to a dithiolene group present in the pterin-based 6-alkyl side chain of molybdopterin (MPT). Molybdopterins are a class of cofactors found in most molybdenum-containing and all tungsten-containing enzymes. Synonyms for molybdopterin are: MPT and pyranopterin-dithiolate. The nomenclature for this biomolecule can be confusing: Molybdopterin itself contains no molybdenum; rather, … Meer weergeven Unlike many other cofactors, molybdenum cofactor (Moco) cannot be taken up as a nutrient. The cofactor thus requires de novo biosynthesis. Molybdenum cofactor biosynthesis occurs in four steps: (i) the radical … Meer weergeven Some bacterial oxidoreductases use tungsten in a similar manner as molybdenum by using it in a tungsten-pterin complex, with molybdopterin. Thus, molybdopterin … Meer weergeven • Molybdenum cofactor deficiency, a genetic illness. • MOCOS, molybdenum cofactor sulfurase • MOCS1, MOCS2, MOCS3, GEPH Meer weergeven Enzymes that use molybdopterin as cofactor or prosthetic group are given below.
