Biosynthesis of molybdenum cofactor
WebMolybdenum is a trace element that functions as a cofactor for at least 4 enzymes: sulfite oxidase, xanthine oxidase, aldehyde oxidase, and mitochondrial amidoxime reducing component. In each case, molybdenum is bound to a complex, multiring organic component called molybdopterin, forming the entity molybdenum cofactor.

WebAug 1, 2002 · With the exception of the bacterial nitrogenase, Mo is bound to a unique pterin compound named molybdenum cofactor (Moco; Fig. 1 A) which binds to diverse apoproteins. These Mo‐enzymes participate in essential redox reactions in the global C‐, N‐, and S‐cycles ( Hille, 1996 ). The Moco occurs ubiquitously in all organismic kingdoms. WebMay 31, 2024 · All of the different cofactors are synthesized from FRAME: CPD-4 (MPT). The variability of the molybdenum cofactors found in bacteria is achieved by the attachment of GMP, AMP, IMP, or CMP to the phosphate group of MPT. The MPT structure is conserved in all organisms and it has been demonstrated that its biosynthesis is …

This article … WebThe transition element molybdenum needs to be complexed by a special cofactor to gain catalytic activity. Molybdenum is bound to a unique pterin, thus forming the …
Web3.1.3. Metabolism. Molybdenum exists in several valence states and may undergo oxidation and reduction. The primary form of molybdenum that interacts with enzyme systems is Mo VI, as the molybdate anion (Mo VI O 2 2−) (Nakanishi et al. 2013).After molybdate is taken into a cell, it is incorporated into a molybdopterin to form … WebAbstractThe molybdenum cofactor (Moco) forms the active site of all eukaryotic molybdenum (Mo) enzymes. Moco consists of molybdenum covalently bound to two sulfur atoms of a unique tricyclic pterin moiety referred to as molybdopterin. Moco is synthesized from GTP by an ancient and conserved biosynthetic pathway that can be divided into …
