metülaatsioon
Metülaatsioon is a fundamental biochemical process that involves the transfer of a methyl group, typically from a methyl donor molecule such as S-adenosylmethionine (SAM), to a substrate. This seemingly simple addition of a single carbon atom and three hydrogen atoms plays a critical role in a vast array of biological functions across all living organisms.
In humans and other eukaryotes, metülaatsioon is crucial for gene expression regulation. DNA metülaatsioon, specifically the
Beyond gene regulation, metülaatsioon is involved in protein function modification, neurotransmitter synthesis and metabolism, detoxification processes,
