L-Methionine had no behavioral effects in normal humans and failed to increase concentrations of S-adenosylmethionine (methyl donor) in human or rat blood, while increasing rat liver levels more than fivefold. Methionine or S-adenosylmethionine in very high doses had almost no effect on methylation of tritiated levodopa in rodent tissues; various ...

Partial methylation of methyl glycosides
Chemistry of Natural Compounds, 1975The partial methylation of methyl xylo-, arabino-, lyxo- and rhamnopyranosides by Purdie's method has been studied; it is possible to use the results obtained for the isolation of individual methyl ethers by micro-preparative GLC.

The methylation of tRNA is a post-transcriptional modification which is achieved by specific enzymes, the tRNA methylases, with S adenosylmethionine as a methyl donor. The level and pattern of methylation are characteristic of the tRNA species and origin. Abnormally methylated tRNAs have been obtained, in vivo and in vitro, by a variety of methods, and
