WebFeb 10, 2024 · HNMT is an enzyme catalysing the transfer of a methyl group from S-adenosyl- l -methionine (SAM) to histamine, yielding Nτ -methylhistamine and S-adenosyl- l -homocysteine ( Figure 2 ). The human HNMT gene was cloned by Girard et al. in 1994 and encodes a 33 kDa protein consisting of 292 amino acids [ 39] ( Table 1 ).

WebFeb 10, 2024 · Histamine N-Methyltransferase in the Brain Brain histamine is a neurotransmitter and regulates diverse physiological functions. Previous studies have … Web29-Jan-2024 Summary In mammals, histamine is metabolized by two major pathways: N(tau)-methylation via histamine N-methyltransferase and oxidative deamination via diamine oxidase. This gene encodes the first enzyme which is found in the cytosol and uses S-adenosyl-L-methionine as the methyl donor.
WebMay 26, 2024 · Histamine is metabolized almost entirely via 2 major pathways. In the first, histamine N-methyltransferase metabolizes most of the histamine to NMH, and monoamine oxidase (MAO) then metabolizes NMH to M-methyl imidazole acetic acid. In the second, diamine oxidase metabolizes 15%-30% of the histamine to imidazole acetic acid. WebHistamine N-methyltransferase (HNMT) catalyzes the N tau-methylation of histamine. N tau-Methylhistamine can then undergo oxidation catalyzed by the mitochondrial enzyme monoamine oxidase (MAO). Addition of an MAO inhibitor such as pargyline to tissue preparations can increase the HNMT activity assayed --presumably as a result of …
