| 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) |
