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.

Expression of the Arabidopsis CGS1 gene, encoding the first committed enzyme of methionine biosynthesis, is feedback-regulated in response to S-adenosyl-L-methionine (AdoMet) at the mRNA level. This regulation is first preceded by temporal arrest of CGS1 translation elongation at the Ser-94

Critical reviews in biochemistry and molecular biology, 47(2), 97-193 (2012-01-21)
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

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

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

We have recently isolated two Arabidopsis thaliana DNA hypomethylation mutations, identifying the DDM1 locus, that cause a 70% reduction in genomic 5-methylcytosine levels [1]. Here we describe further phenotypic and biochemical characterization of the ddm1 mutants. ddm1/ddm1 homozygotes exhibited altered
