| serine-trna ligase | <enzyme> An enzyme that activates serine with its specific transfer RNA. Chemical name: L-Serine:tRNA(Ser) ligase (AMP-forming) Registry number: EC 6.1.1.11 (12 Dec 1998) |
|---|---|
| succinyl-CoA ligase | A ligase reversibly reacting succinate and CoA with ATP to produce ADP, inorganic phosphate, and succinyl-CoA, a similar synthetase, but one able to use itaconate as well as succinate and GTP (or ITP) in place of ATP; a part of the tricarboxylic acid cycle. Synonym: succinic thiokinase, succinyl-CoA ligase. (05 Mar 2000) |
| DNA ligase | <enzyme, molecular biology> Enzyme involved in DNA replication. The DNA ligase of E. Coli seals nicks in one strand of double stranded DNA, a reaction required for linking precursor fragments during discontinuous synthesis on the lagging strand. Nicks are breaks in the phosphodiester linkage that leave a free 3_ OH and 5_ phosphate. The ligase from phage T4 has the additional property of joining two DNA molecules having completely base paired ends. DNA ligases are crucial in joining DNA molecules and preparing radioactive probes (by nick translation) in recombinant DNA technology. (18 Nov 1997) |
| IMP-aspartate ligase | <enzyme> A carbon-nitrogen ligase. During purine ribonucleotide biosynthesis, this enzyme catalyses the synthesis of adenylosuccinate from GTP, imp, and aspartate with the formation of orthophosphate and GDP. Chemical name: IMP:L-aspartate ligase (GDP-forming) Registry number: EC 6.3.4.4 (12 Dec 1998) |
| isoleucine-trna ligase | <enzyme> An enzyme that activates isoleucine with its specific transfer RNA. Chemical name: L-Isoleucine:tRNA(Ile) ligase (AMP-forming) Registry number: EC 6.1.1.5 (12 Dec 1998) |
| threonine-trna ligase | <enzyme> An enzyme that activates threonine with its specific transfer RNA. Chemical name: L-Threonine:tRNA(Thr) ligase (AMP-forming) Registry number: EC 6.1.1.3 (12 Dec 1998) |
| tRNA excision ligase | <enzyme> Processes pre-trna-tyr into mature trna-tyr Registry number: EC 6.5.1.- (26 Jun 1999) |
| tRNA splicing ligase | <enzyme> One of two enzymes involved in trna splicing in archaea Registry number: EC 6.5.1.- (26 Jun 1999) |
| tryptophan-trna ligase | <enzyme> An enzyme that activates tryptophan with its specific transfer RNA. Chemical name: L-Tryptophan:tRNA(Trp) ligase (AMP-forming) Registry number: EC 6.1.1.2 (12 Dec 1998) |
| tubulin-tyrosine ligase | <enzyme> An enzyme that covalently links a tyrosine to the C-terminal glutamyl residue of tubulin, coupled with the hydrolysis of ATP to ADP and Pi; this is a unique posttranslational modification that may have a significant role in cytoskeletal traffic and design. (05 Mar 2000) |
| tyrosine-trna ligase | <enzyme> An enzyme that activates tyrosine with its specific transfer RNA. Chemical name: L-Tyrosine:tRNA-(Tyr) ligase (AMP-forming) Registry number: EC 6.1.1.1 (12 Dec 1998) |
| tyrosyltubulin ligase | <enzyme> Catalyses reversible, post-translational addition of tyrosine, phenylalanine or dopa to carboxyl terminal of alpha-chain of tubulin Registry number: EC 6.3.2.- Synonym: tubulin-tyrosine ligase, tyrosyl tubulin ligase (26 Jun 1999) |
| ubiquitin-calmodulin ligase | <enzyme> Covalentyl links ubiquitin to bovine calmodulin in an ATP-dependent manner Registry number: EC 6.3.2.21 Synonym: ubiquityl-calmodulin synthetase (26 Jun 1999) |
| ubiquitin-protein ligase | <enzyme> Consists of 3 enzymes; e1 is ubiquitin activating enzyme; e2 transfers activated ubiquitin as an enzyme-ubiquitin thiol ester to e3, which transfers ubiquitin to an intracellular protein; e1 forms both an enzyme-bound cooh-terminal ubiquitin thiolester and a cooh-terminal ubiquitin-adenylatte; ube1y is putative y function in spermatogonial proliferation; ube1x and ube1y encode the e1 enzyme Registry number: EC 6.3.2.19 Synonym: ubiquitin-protein ligase system, ubiquitin-protein-lysine n-omega-ligase, ubiquitin-activating enzyme, ubiquitin-activating enzyme e1, ubiquitination activating enzyme e1, ube1 gene product, rsp5 ubiquitin-protein ligase, npi1 protein, ube1y gene product, ube1x gene product, ikappab-ubiquitin ligase (26 Jun 1999) |
| UDP-N-acetylmuramoylalanine-D-glutamate ligase | <enzyme> From E coli; catalyses the synthesis of udp-n-acetylmuramoyl-l-alanyl-d-glutamate from ATP and udp-n-acetylmuramoyl-l-alanine and d-glutamate Registry number: EC 6.3.2.9 Synonym: d-glu-adding enzyme, d-glutamic acid adding enzyme, murd gene product (26 Jun 1999) |
