| histone | <molecular biology> Protein found in the nuclei of all eukaryotic cells where they are complexed to DNA in chromatin and chromosomes. They are of relatively low molecular weight and are basic, having a very high arginine/lysine content. They are highly conserved and can be grouped into five major classes. Two copies of H2A, H2B, H3 and H4 bind to about 200 base pairs of DNA to form the repeating structure of chromatin, the nucleosome, with H1 binding to the linker sequence. They may act as non-specific repressors of gene transcription. (18 Nov 1997) |
|---|---|
| histone bases | The alpha-amino acids arginine, histidine, and lysine, which are basic by virtue of the presence in the side chains of a guanidine, imidazole, and amine group, respectively; the term "hexone" is a misnomer since histidine does not have six carbons. (05 Mar 2000) |
| histone deacetylase | <enzyme> Hydrolyzes n-acetyl groups on histones. Registry number: EC 3.5.1.- (12 Dec 1998) |
| histone gene | A histone gene is any gene which codes for histone proteins. (Histones help compact DNA so that it will fit into an eukaryotic cells nucleus). (09 Oct 1997) |
| histone h2b kinase | <enzyme> 96 kD serine kinase from xenopus that phosphorylates histone h2b; a component or target of the raf-mek-erk pathway Registry number: EC 2.7.1.- Synonym: p96(h2bk) (26 Jun 1999) |
| histone-lysine n-methyltransferase | <enzyme> An enzyme that catalyses the methylation of the epsilon-amino group of lysine residues in proteins to yield epsilon mono-, di-, and trimethyllysine. Chemical name: S-Adenosyl-L-methionine:histone-L-lysine N(6)-methyltransferase Registry number: EC 2.1.1.43 (12 Dec 1998) |
| histonectomy | Synonym: periarterial sympathectomy. Origin: histo-+ G. Ektome, excision (05 Mar 2000) |
| histones | Proteins associated with DNA in chromosomes. (12 Dec 1998) |
| histoneurology | The microscopic anatomy of the nervous system. Synonym: histoneurology. (05 Mar 2000) |
| histonomy | A law of the development and structure of the tissues of the body. Origin: histo-+ G. Nomos, law (05 Mar 2000) |
| histonuria | The excretion of histone in the urine, as observed in certain instances of leukaemia, febrile illnesses, and wasting diseases. Origin: histone + G. Ouron, urine (05 Mar 2000) |
