Aplicación

S-(5′-Adenosyl)-L-methionine (SAM, AdoMet) is used as a primary methyl donor molecule in mammalian cell culture and the first step metabolite in methionine biosynthesis.

Acciones bioquímicas o fisiológicas

Methyl donor; cofactor for enzyme-catalyzed methylations, including catechol O-methyltransferase (COMT) and DNA methyltransferases (DNMT). Although present in all cells, it is concentrated in liver where 85% of all methylation reactions occur. It is also involved in regulating liver function, growth, and response to injury.

Precaución

This material is very unstable at room temperature.

Human catechol-O-methyltransferase (COMT) catalyzes a methyl transfer from S-adenosylmethionine (AdoMet) to dopamine. Site-specific mutants at three positions (Tyr68, Trp38, and Val108) have been characterized with regard to product distribution, catalytic efficiency, and secondary kinetic isotope effects. The series of mutations

S-Adenosylmethionine, abbreviated as SAM, SAMe or AdoMet, is the principal methyl group donor in the mammalian cell and the first step metabolite of the methionine cycle, being synthesized by MAT (methionine adenosyltransferase) from methionine and ATP. About 60 years after

The sequence-specific transfer of methyl groups from donor S-adenosyl-L-methionine (AdoMet) to certain positions of DNA-adenine or -cytosine residues by DNA methyltransferases (MTases) is a major form of epigenetic modification. It is virtually ubiquitous, except for some notable exceptions. Site-specific methylation

DNA methyltransferases are important enzymes and their inhibition has many potential applications. The investigation of DNA methyltransferases as well as screening for potential inhibitors requires specialized enzyme assays. In this chapter, we describe three DNA methyltransferase assays, each of them

Radical S-adenosylmethionine (AdoMet) enzymes comprise a large superfamily of proteins that engage in a diverse series of biochemical transformations through generation of the highly reactive 5'-deoxyadenosyl radical intermediate. Recent advances into the biosynthesis of unique iron-sulfur (FeS)-containing cofactors such as
