| 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) |

| hydroxycinnamoyl-CoA-tyramine N-(hydroxycinnamoyl)transferase | <enzyme> Catalyses synthesis of n-(hydroxycinnamoyl)tyramine; isolated from nicotiana tabacum Registry number: EC 2.3.1.- Synonym: tht enzyme (26 Jun 1999) |
| 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) |
| succinyl-CoA-3-hydroxy-3-methylglutarate CoA transferase | <enzyme> Rat liver mitochondrial enzyme which catalyses transfer of a conezyme a molecule from succinyl-CoA to 3-hydroxy-3-methylglutarate Registry number: EC 2.8.3.- Synonym: succinylcoa-hmg CoA transferase, sca-hmg cat (26 Jun 1999) |
| succinyl CoA propionate CoA-transferase | <enzyme> Succinyl CoA and propionate gives propionyl CoA and succinate Registry number: EC 2.8.3.- Synonym: succinyl coenzyme a propionate coenzyme a-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) |
| D-amino acid transferase | <enzyme> Mw 41 kD; catalyses d-amino acid transfer; d-configuration specific; recognises aromatic d-amino acid esters to form oligo d-amino acid esters Registry number: EC 2.3.2.- (26 Jun 1999) |
| deoxynucleoside diphosphate-oligonucleotide deoxynucleotidyl transferase | <chemical> Activated by mg++ Synonym: dndp-deoxynucleotidyl transferase, ddodt (26 Jun 1999) |
| dimethylallylpyrophosphate-trihydroxypterocarpan dimethylallyl transferase | <enzyme> Involved in pyroalexin biosynthesis, forms glyceollin rings Registry number: EC 2.5.1.- (26 Jun 1999) |
| dipeptidyl transferase | Cleaving dipeptides from the amino end of polypeptides. See: dipeptidyl peptidase. (05 Mar 2000) |
| telomere terminal transferase | <enzyme> From oxytricha nova; adds two to seven tandem repeats of the sequence ggggtttt to the 3' end of oligonucleotide primers ending in repeats of g4t4 and always adds the repeats in the proper phase Registry number: EC 2.7.7.- (26 Jun 1999) |
| terminal transferase | <enzyme> An enzyme adds a particular nucleotide to the 3' end of DNAstrands. (09 Oct 1997) |
