Histone Methylation: Recognizing the Methyl Mark
2003Publisher 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 ...

Synthesis of methyl ethers of methyl (methyl ?-D-mannopyranosid)-uronate [PDF]
Chemistry of Natural Compounds, 1987 Methyl (methyl α-D-mannopyranosid)uronate (I) has been obtained by the catalytic oxidation of methyl α-D-mannopyranoside with oxygen in the presence of platinum carbon with a yield of 20%. The partial methylation of (I) and preparative column chromatography on silica gel has provided a convenient method of obtaining all the methyl ethers of (I) in the ...

S-adenosylmethionine (SAM) has antidepressant properties. The commonest neuropsychiatric complication of severe folate deficiency is depression. These independent observations suggest that methylation in the nervous system may underlie the expression of mood and related processes and may be implicated in some affective disorders; suggest new biological

S‐Adenosylmetliionine and methylation
The FASEB Journal, 1996S-Adenosylmethionine (AdoMet or SAM) plays a pivotal role as a methyl donor in a myriad of biological and biochemical events. Although it has been claimed that AdoMet itself has therapeutic benefits, it remains to be established whether it can be taken up intact by cells.

The synthesis of methyl tetrosides and their methyl ethers
Collection of Czechoslovak Chemical Communications, 1980Methyl α- and β-D-threofuranosides (I and II) and methyl α- and β-D-erythrofuranosides (VII and VIII) were prepared in a modified manner. For the preparation of monomethyl ethers of compounds I and II 1,2-O-isopropylidene-β-D-threofuranose (IV) was prepared as the starting compound.

The Journal of Chemical Thermodynamics, 2019
Abstract The experimental measurements for liquid viscosities of four fatty acid methyl esters, including methyl hexanoate, methyl heptanoate, methyl caprylate, and methyl nonanoate, were carried out with a falling-cylinder viscometer. For the present measurement, the temperature ranges were from 292 K to 362 K and the pressure was reached to 30 MPa.
