23S rRNA (uracil 1939-C 5)-methyltransferase (EC 2.1.1.190, RumA, RNA uridine methyltransferase A, YgcA) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (uracil 1939-C 5)-methyltransferase.
The Methionine Synthase Reductase (MTRR) gene primarily acts in the reductive regeneration of cob(I)alamin (vitamin B12). [10] Cob(I)alamin is a cofactor that maintains activation of the methionine synthase enzyme (MTR) Methionine synthase, linking folate and methionine metabolism. Donation of methyl groups from folate are utilized for cellular ...

[Methionine synthase] reductase, or Methionine synthase reductase, [1] encoded by the gene MTRR, is an enzyme that is responsible for the reduction of methionine synthase inside human body. This enzyme is crucial for maintaining the one carbon metabolism, specifically the folate cycle .
The methylation reaction catalyzed by methionine synthase. Methionine synthase regenerates methionine (Met) from homocysteine (Hcy). The overall reaction transforms 5-methyltetrahydrofolate (N 5-MeTHF) into tetrahydrofolate (THF) while transferring a methyl group to Hcy to form Met. Methionine Syntheses can be cobalamin-dependent and cobalamin ...
S-Adenosylmethionine synthetase (EC 2.5.1.6), also known as methionine adenosyltransferase (MAT), is an enzyme that creates S-adenosylmethionine (also known as AdoMet, SAM or SAMe) by reacting methionine (a non-polar amino acid) and ATP (the basic currency of energy).
First, methionine receives an adenosine group from ATP, a reaction catalyzed by S-adenosyl-methionine synthetase, to give S-adenosyl methionine (SAM-e). SAM-e then transfers the methyl group to an acceptor molecule, (e.g., norepinephrine as an acceptor during epinephrine synthesis, DNA methyltransferase as an intermediate acceptor in the ...
23S rRNA (adenosine 1067-2'-O)-methyltransferase (EC 2.1.1.230, 23S rRNA A1067 2'-methyltransferase, thiostrepton-resistance methylase, nosiheptide-resistance methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:23S rRNA (adenosine 1067-2'-O)-methyltransferase.
