Qu'est-ce (qui) est 2′-O-methylation - définition
2′-O-methylation
![2'-''O''-methyl-adenosine, a modified [[adenosine]].](https://commons.wikimedia.org/wiki/Special:FilePath/2'-O-Methyladenosine.svg?width=200 "2'-''O''-methyl-adenosine, a modified [[adenosine]].")
2′-O-methylation is a common nucleoside modification of RNA, where a methyl group is added to the 2′ hydroxyl of the ribose moiety of a nucleoside, producing a methoxy group. 2′-O-methylated nucleosides are mostly found in ribosomal RNA and small nuclear RNA and occur in the functionally essential regions of the ribosome and spliceosome.

Protein methylation
THE ADDITION OF A METHYL GROUP TO A PROTEIN AMINO ACID. A METHYL GROUP IS DERIVED FROM METHANE BY THE REMOVAL OF A HYDROGEN ATOM.
User:Tehnextallstar/sandbox; Draft:Protein methylation
Protein methylation is a type of post-translational modification featuring the addition of methyl groups to proteins. It can occur on the nitrogen-containing side-chains of arginine and lysine, but also at the amino- and carboxy-termini of a number of different proteins.
