| formate-tetrahydrofolate ligase | <enzyme> An enzyme that catalyses the formation of 10-formyltetrahydrofolate from formate and tetrahydrofolate in the presence of ATP. This enzyme has been found in pigeon liver, human erythrocytes and some microorganisms. Chemical name: Formate:tetrahydrofolate ligase (ADP-forming) Registry number: EC 6.3.4.3 (12 Dec 1998) |
| leucine-trna ligase | <enzyme> An enzyme that activates leucine with its specific transfer RNA. Chemical name: L-Leucine:tRNA(Leu) ligase (AMP-forming) Registry number: EC 6.1.1.4 (12 Dec 1998) |
| ligase | <enzyme, molecular biology> Major class of enzymes that catalyse the linking together of two molecules (category 6 in the I.U.B.C.E. Nomenclature) for example DNA ligases that link two fragments of DNA by forming a phosphodiester bond. (18 Nov 1997) |
| ligase amplification reaction | <molecular biology> Method for detecting small quantities of a target DNA, with utility similar to PCR. It relies on DNA ligase to join adjacent synthetic oligonucleotides after they have bound the target DNA. Their small size means that they are destabilised by single base mismatches and so form a sensitive test for the presence of mutations in the target sequence. (18 Nov 1997) |

| lipoate-protein ligase | <enzyme> Involved in post-translation modification by n6-lipoylation of lysine residues of the lipoate acyltransferase subunits of 2-oxoglutarate dehydrogenase and pyruvate dehydrogenase complexes Registry number: EC 6.3.2.- Synonym: lipoyl-protein ligase (26 Jun 1999) |
| long-chain-fatty-acid-(acyl-carrier-protein) ligase | <enzyme> Fatty acid, acyl-carrier-protein-sh and ATP gives acyl-(acyl-carrier-protein), AMP and ppi Registry number: EC 6.2.1.20 Synonym: fatty acid-acyl carrier protein ligase (AMP), acyl-(acyl-carrier-protein)synthetase, aacp synthetase, fatty acyl-acyl carrier protein synthase, vibrio harveyi, acyl-(acyl-carrier-protein) synthetase, acyl-acp synthetase (26 Jun 1999) |
| long-chain-fatty-acid-CoA ligase | <enzyme> Fatty acid thiokinase (long-chain), a ligase forming acyl-CoA, AMP, and pyrophosphate from long-chain fatty acids, ATP, and coenzyme A.

| lysine-trna ligase | <enzyme> An enzyme that activates lysine with its specific transfer RNA. Chemical name: L-Lysine:tRNA(Lys) ligase (AMP-forming) Registry number: EC 6.1.1.6 (12 Dec 1998) |
| acceptor RNA | rNA |
| antisense RNA | <molecular biology> A complementary RNA sequence that binds to (and thus blocks the transcription of) a naturally-occuring (sense) messenger RNA molecule. These proteins can be used to selectively turn off production of certain proteins or block viral genetic instructions, by marking them for destruction by cellular enzymes, in order to prevent the building of new virus or the infection of new cells.
