Commercial homocysteine methyltransferase
WebThe function of BHMT is to transfer the methyl group from betaine to homocysteine, thereby forming dimethylcysteine and methionine. Mutations in the BHMT gene have been reported in breast cancer. To study the effect of mutations in BHMT, knockout mice of this gene were generated and functionally characterized. WebHomocysteine levels depend on its synthesis, involving methionine adenosyltransferase, S-adenosylmethionine-dependent methyltransferases such as glycine N-methyltransferase, and S-adenosylhomocysteine hydrolase; its remethylation to methionine by methionine synthase, which requires methionine synthase reductase, vitamin B (12), and …

WebHomocysteine (Hcy) is a thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of folic acid, vitamins B6 and B12. WebSep 8, 2015 · Seafood is assumed to be beneficial for cardiovascular health, mainly based on plasma lipid lowering and anti-inflammatory effects of n-3 polyunsaturated fatty acids. However, other plasma risk factors linked to cardiovascular disease are less studied. This study aimed to penetrate the effect of a phospholipid-protein complex (PPC) from …

WebMethyltransferases are a large group of enzymes that all methylate their substrates but can be split into several subclasses based on their structural features. The most common class of methyltransferases is class I, all of which contain a Rossmann fold for binding S -Adenosyl methionine (SAM). Class II methyltransferases contain a SET domain ...
