Biological methylation

Quarterly Reviews, Chemical Society, 1945
SummaryThe enzymatic methylation or demethylation of naturally occurring compounds represents significant metabolic processes which have gained additional interest since the discovery of a mechanism by means of which methyl groups can be transferred from one compound to another.The capacity to transfer methyl groups is confined to a fewN‐and S ...

Monoepoxidation of methyl linoleate: (±)‐methyl vernolate and (±)‐methyl coronarate

Journal of the American Oil Chemists' Society, 1968
AbstractThe two monoepoxides resulting from the epoxidation of methyl linoleate with monoperphthalic acid have been separated from each other by column chromatography. Degradation reactions on each of these established that the separation occurred without concomitant rearrangement of the double bond or the epoxide ring.

High-Temperature Measurements of the Reactions of OH with Small Methyl Esters: Methyl Formate, Methyl Acetate, Methyl Propanoate, and Methyl Butanoate

The Journal of Physical Chemistry A, 2012
The overall rate constants for the reactions of hydroxyl radicals (OH) with four small methyl esters, namely methyl formate (CH(3)OCHO), methyl acetate (CH(3)OC(O)CH(3)), methyl propanoate (CH(3)OC(O)C(2)H(5)), and methyl butanoate (CH(3)OC(O)C(3)H(7)), were investigated behind reflected shock waves using UV laser absorption of OH radicals near 306.69 ...

Histone Methylation: Recognizing the Methyl Mark

2003
Publisher Summary Histone N-terminal tails are subject to a variety of covalent modifications that ultimately affect chromatin structure. One such modification is N-methylation, which occurs on Lys (K) and Arg (R) amino acids. The enzymes performing these modifications are the histone N-methyl transferases (HMTs) that catalyze the transfer of a ...
