S-Adenosyl methionine (SAM), also known under the commercial names of SAMe, SAM-e, or AdoMet, is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation. Although these anabolic reactions occur throughout the body, most SAM is produced and consumed in the liver. [ 1 ]
The systematic name of this enzyme class is S-adenosyl-L-methionine:1D-myo-inositol 4-methyltransferase. Other names in common use include myo-inositol 4-O-methyltransferase, S-adenosyl-L-methionine:myo-inositol 4-O-methyltransferase, and myo-inositol 6-O-methyltransferase.
The systematic name of this enzyme class is S-adenosyl-L-methionine hydrolase. Other names in common use include S-adenosylmethionine cleaving enzyme , methylmethionine-sulfonium-salt hydrolase , and adenosylmethionine lyase .
S-adenosyl-L-methionine + isoliquiritigenin S-adenosyl-L-homocysteine + 2'-O-methylisoliquiritigenin. Thus, the two substrates of this enzyme are S-adenosyl methionine and isoliquiritigenin, whereas its two products are S-adenosylhomocysteine and 2'-O-methylisoliquiritigenin.
Adenylosuccinate lyase deficiency is responsible for a range of symptoms that involve psychomotor retardation, often accompanied by epileptic seizures, and autistic features. Two common theories were proposed to account for these effects, the first is that they result from decreased concentrations of purine nucleotides needed for purine ...
Sarcosine/dimethylglycine N-methyltransferase (EC 2.1.1.157, ApDMT, sarcosine-dimethylglycine methyltransferase, SDMT, sarcosine dimethylglycine N-methyltransferase, S-adenosyl-L-methionine:N,N-dimethylglycine N-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:sarcosine(or N,N-dimethylglycine) N-methyltransferase (N,N-dimethylglycine(or betaine)-forming).
The systematic name of this enzyme class is S-adenosyl-L-methionine:tRNA (guanine-N1-)-methyltransferase. Other names in common use include transfer ribonucleate guanine 1-methyltransferase, tRNA guanine 1-methyltransferase, and S-adenosyl-L-methionine:tRNA (guanine-1-N-)-methyltransferase.
The systematic name of this enzyme class is S-adenosyl-L-methionine:glycine N-methyltransferase. Other names in common use include glycine methyltransferase, S-adenosyl-L-methionine:glycine methyltransferase, and GNMT. This family of enzymes participates in the metabolism of multiple amino acids.
