| cyanocobalamin beta-ligand transferase | <enzyme> Cytosolic enzyme utilizing fad, NADPH and reduced glutathione; forms glutathionylcobalamin from cyanocobalamin Registry number: EC 2.5.1.- Synonym: ccbl transferase (26 Jun 1999) |
| histo-blood group B transferase | <enzyme> Catalyses transfer of galactose from udp-galactose to glycoproteins and glycolipids; differs from a transferase by four amino acid residues Registry number: EC 2.4.1.- Synonym: b transferase, histo-blood group (26 Jun 1999) |
| selenium transferase | <enzyme> Converts phosphoseryl-trna to selenocysteinyl-trna; product of sela gene; converts seryl-trna(sec)(uca) to selenocysteyl-trna(sec)(uca) in pyridoxal-phosphate dependent reaction Registry number: EC 2.- Synonym: se-transferase, selenocysteine synthase (26 Jun 1999) |
| pyrimidine transferase | <enzyme> An enzyme catalyzing transfer of a pyridine or other bases into the position of the pyrimidine in thiamin; e.g., thiamin reacting with pyridine produces heteropyrithiamin and 4-methyl-5-(2'-hydroxyethyl)-thiazole. Synonym: pyrimidine transferase, thiaminase I. (05 Mar 2000) |
| hypoxanthine-guanine phosphoribosyl transferase | <enzyme> An enzyme which plays an important role in the making of ATP and GTP from guanine -- the only way guanine, adenine, or other purine molecules are able to become part of nucleic acids. Biologists study gene action via the incorporation of modified nitrogenous bases into DNA by manipulating the metabolic role which this enzyme plays. Similarly, the enzyme thymidine kinase is used for the same purpose by biologists because it fills the same important and unique role for the pyrimidines (thymine, cytosine, uracil, etc.). Acronym: HGPRT (09 Oct 1997) |
| N-acetylmannosaminuronic acid transferase | <enzyme> From salmonella typhimurium; catalyses the transfer of n-acetylmannosaminuronic acid from udp-mannaca to lipid i Registry number: EC 2.4.1.- Synonym: udp-n-acetylmannosaminuronic acid transferase, udp-mannaca transferase (26 Jun 1999) |
| NAD transferase | <enzyme> Catalyses phosphorylation of host bacterial proteins Registry number: EC 2.7.7.- (26 Jun 1999) |
| nonaprenyl-4-hydroxybenzoate transferase | <enzyme> Ph optimum 7.5; completely inhibited by triton x-100 and deoxycholate, but not by taurodeoxycholate and beta-octyl glucoside; mediates the transfer of the polyisoprenoid side chain to 4-hydroxybenzoate in ubiquinone biosynthesis Registry number: EC 2.5.1.- Synonym: n4hb transferase (26 Jun 1999) |
| nucleotide pyrophosphate transferase | <enzyme> Transfers the beta, gamma pyrophosphate group from ATP to 3'-hydroxy group of ribonucleotides, oligonucleotides or trna Registry number: EC 2.7.6.- (26 Jun 1999) |
