It is also a methyl donor of increasingly recognised significance in biology.

These diets may include supplementation with methyl donors, such as folate.

Choline functions as a methyl donor and it is required for proper liver function.

S-adenosyl methionine acts as the methyl donor.

Speculated roles include methionine storage, use as a methyl donor, regulation of SAM.

S-adenosylmethionine is a methyl donor and allows DNA methylation.

S-adenosylmethionine (SAM) may serve as methyl donor.

The resulting product is a methyl donor that is required for CpG and histone methylation.

Its derivative S-adenosyl methionine (SAM) serves as a methyl donor.

This process uses N5-methyl tetrahydrofolate as the methyl donor and cobalamin (vitamin B)-related enzymes.

The protein encoded by this gene is a methyltransferase that converts guanidoacetate to creatine, using S-adenosylmethionine as the methyl donor.

Some radical SAM enzymes use a second SAM as a methyl donor.

His final work showed that methionine is the only methyl donor in mammalian metabolism, and that there is no pool of methyl groups.

For instance, deficiencies of the main dietary sources of methyl donors, methionine and choline, lead to the formation of liver cancer in rodents.

Folate is also necessary to make s-adenosylmethionine (SAM), which acts as a methyl donor in the synthesis of DNA.

All the known DNA methyltransferases use S-adenosyl methionine (SAM) as the methyl donor.

Methytransferases use a reactive methyl group bound to sulfur in S-adenosyl methionine (SAM) as the methyl donor.

Three molecules are involved in the Dcm-catalysed methylation reaction, substrate DNA, the enzyme itself and SAM, the methyl donor.

In both types of histone methyltransferases, cofactor S-Adenosyl methionine (SAM) serves as a cofactor and methyl donor group.

Regeneration of functional enzyme requires reductive methylation via a reaction catalyzed by (methionine synthase) reductase in which S-adenosylmethionine is utilized as a methyl donor.

Methionine is an essential amino acid that must be provided by dietary intake of proteins or methyl donors (choline and betaine found in beef, eggs and some vegetables).

It does so by combining the hydrogen donor coenzyme B and the methyl donor coenzyme M. Via this enzyme, most of the natural gas on earth was produced.

S-adenosylhomocysteine (SAH) is the resultant product following the release of a methyl group from s-adenosylmethionine (SAM), a universal methyl donor [ 23 ] .

Arginine methylation is an apparently irreversible protein modification catalyzed by arginine methyltransferases, such as PMT7, using S-adenosylmethionine (AdoMet) as the methyl donor.

It was followed by a study that showed that genistein and methyl donor supplementation can counteract detrimental epigenetic effects induced by a controversial xenobiotic chemical, bisphenol A (BPA).
