Biosynthesis of molybdenum cofactor
WebAug 12, 2009 · Molybdenum enzymes with a pterin cofactor. More than 50 different pterin-containing molybdenum enzymes are known and … 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. 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 …
WebJan 1, 2024 · Molybdenum cofactor (Moco) biosynthesis is an ancient and highly conserved pathway. • Various gene fusions gave rise to novel protein functions. • Alternative splicing regulates MOCS1 and gephyrin properties. • The radical SAM enzyme MOCS1A receives [4 Fe-4 S] in the cytosol and mitochondria. • WebAbstract Molybdenum cofactor (Moco) is essential for nitrate reductase (NR), xanthine dehydrogenase (XDH), and aldehyde oxidase to perform their catalytic functions in …
WebMolybdenum cofactor deficiency is a rare metabolic disorder characterized by severe and rapidly progressive neurologic damage caused by the functional loss of sulfite oxidase, one of four molybdenum-dependent enzymes. Until recently, no effective therapy was available, and early fatality was the usual outcome. WebMay 5, 2005 · The human MOCS3 protein contains an N-terminal domain similar to the Escherichia coli MoeB protein and a C-terminal segment displaying similarities to the sulfurtransferase rhodanese. MOCS3 is proposed to catalyze both the adenylation and the subsequent generation of a thiocarboxylate group at the C-terminus of the smaller …
