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 ]
S-Adenosylmethionine synthetase (EC 2.5.1.6), also known as methionine adenosyltransferase (MAT), is an enzyme that creates S-adenosylmethionine (also known as AdoMet, SAM or SAMe) by reacting methionine (a non-polar amino acid) and ATP (the basic currency of energy). [1]
The M (hsdM) and S subunits together form a methyltransferase that methylates two adenine residues in complementary strands of a bipartite DNA recognition sequence. In the presence of the R subunit, the complex can also act as an endonuclease , binding to the same target sequence but cutting the DNA some distance from this site.
S-adenosyl-methionine is prevalent throughout our bodies, in both tissue and fluid, and it plays a number of roles. It's best known for its encouragement of a healthy and stable mood and for its ...
Radical SAM enzymes belong to a superfamily of enzymes that use an iron-sulfur cluster to reductively cleave S-adenosyl-L-methionine (SAM) to generate a radical, usually a 5′-deoxyadenosyl radical (5'-dAdo), as a critical intermediate.
The enzyme adenosylmethionine decarboxylase (EC 4.1.1.50) catalyzes the conversion of S-adenosyl methionine to S-adenosylmethioninamine. Polyamines such as spermidine and spermine are essential for cellular growth under most conditions, being implicated in many cellular processes including DNA, RNA and protein synthesis.
S-adenosyl methionine (SAM) is the precursor to 5′-methylthioadenosine. The pervasive cofactor S-adenosyl methionine (SAM) is the precursor to 5′-methylthioadenosine. The sulfonium group in SAM can cleave in three ways, one involves loss of CH 2 CH 2 CH(NH 3 +)CO 2 −, generating the title compound.
The function of the HNMT enzyme is histamine metabolism by ways of N τ-methylation using S-adenosyl-L-methionine (SAM-e) as the methyl donor, producing N τ-methylhistamine, which, unless excreted, can be further processed by monoamine oxidase B (MAOB) or by diamine oxidase (DAO). Methylated histamine metabolites are excreted with urine. [16] [17]
