Sentence examples for methyl transfer from from inspiring English sources

This would be followed by methyl transfer from the second SAM, producing MeSiA37.

The major difference between MetH and class B RSMTs is the predicted mechanism of methyl transfer from MeCbl to the substrate.

However, recent work shows that methyl transfer from SAM to the enzyme does not depend on Ado radical formation and can proceed in the absence of substrate tRNA suggesting that sulfur insertion may not precede methyl transfer.

MetH catalyzes methyl transfer from methyltetrahydrofolate (Me-FH4) to homocysteine, in which the cobalamin cofactor cycles between MeCbl and cob(I alamin forms, as it is alternately demethylated by homocysteine and remethylated by Me-FH4.

The reaction proceeds by methyl transfer from 5-methyltetrahydrofolate to MS-bound cob(I alamin to form MeCbl, followed by transfer of the methyl group to homocysteine to form methionine and regeneration of cob(I alamin (Refs 109, 110).

Integration of the intact methyl group of l-[methyl-H3]methionine into the pyridinol moiety suggests that methyl transfer from methionine is catalyzed by a SAM-dependent methyltransferase, as opposed to a radical SAM enzyme.

The calculated free energy of activation for the methyl transfer process from designed dimethyl phenyl)sulfonium (1) to aged AChE OP adduct occurs with a barrier of 31.4 kcal/mol at M05-2X/6-31G∗ level of theory, which is 6.4 kcal/mol lower compared to the aging process signifies the preferential reversal process to recover the aged AChE OP adduct.

This is the methyl transfer reaction from the cationic cofactor S-adenosyl l-methionine (SAM) to the catecholate anion which is catalyzed by catechol O-methyl transferase (COMT) [34], and is an SN2 reaction that formally proceeds from charged reactants to neutral products (see Fig. 6).

Following methyl-transfer from SAM to substrates, the product (S -adenosyl- S -adenosyl-ne (SAH) is cleaved by Pfs to produce SRH and adenine.

It was expressed as fmol of [H]-methyl transferred from radioactively labelled DNA to protein per mg of total cell extract protein.

The second energy conservation system, described in A. woodii, suggests that the methyl group transfer from methyl-THF to the carbon monoxide dehydrogenase/acetyl-CoA synthase by a membrane-bound corrinoid protein is accompanied by an efflux of Na+ ions.
