| methylation |
Methylation refers to the replacement of a hydrogen atom (H) with a methyl group (CH3), regardless of the substrate. Methylation can occur in both biological and non-biological systems. In biological systems, methylation is catalyzed by enzymes; such methylation can be involved in modification of heavy metals, regulation of gene expression, regulation of protein function, and RNA metabolism. ...
