5-Methylcytosine
5-Methylcytosine is a methylated form of cytosine in which a methyl group is attached to carbon 5, altering its structure without altering its base-pairing properties.; 5-Methylcytosine is a methylated form of cytosine in which a methyl group is attached to carbon 5, altering its structure without altering its base-pairing properties. -- Wikipedia; 5-Methylcytosine is an epigenetic modification formed by the action of DNA methyltransferases. In bacteria, 5-methylcytosine can be found at a variety of sites, and is often used as a marker to protect DNA from being cut by native methylation-sensitive restriction enzymes. In plants, 5-methylcytosine occurs at both CpG and CpNpG sequences. In fungi and animals, 5-methylcytosine predominately occurs at CpG dinucleotides. Although most eukaryotes methylate only a small percentage of these sites, in vertebrates 70-80\\\% of CpG cytosines are methylated. -- Wikipedia; 5-Methylcytosine is an epigenetic modification formed by the action of DNA methyltransferases. Its function varies significantly among species:; A methylated nucleotide base found in eukaryotic DNA.

1-Methylhistamine
1-Methylhistamine, also known as H137, belongs to the class of organic compounds known as 2-arylethylamines. These are primary amines that have the general formula RCCNH2, where R is an organic group. 1-Methylhistamine exists in all living organisms, ranging from bacteria to humans. Within humans, 1-methylhistamine participates in a number of enzymatic reactions. In particular, S-adenosylhomocysteine and 1-methylhistamine can be biosynthesized from S-adenosylmethionine and histamine; which is mediated by the enzyme histamine N-methyltransferase. In addition, 1-methylhistamine can be converted into methylimidazole acetaldehyde through its interaction with the enzyme amine oxidase [flavin-containing] a. In humans, 1-methylhistamine is involved in histidine metabolism. 1-Methylhistamine is a potentially toxic compound. 1-Methylhistamine is a histamine metabolite. It is a product of histamine 1-methyltransferase [EC 2.1.1.8] in the pathway histidine metabolism (KEGG). [HMDB] Acquisition and generation of the data is financially supported in part by CREST/JST.
