- Isoleucine-tRNA ligase
enzymology, an isoleucine-tRNA ligase (EC number|18.104.22.168) is an enzymethat catalyzes the chemical reaction
:ATP + L-isoleucine + tRNAIle AMP + diphosphate + L-isoleucyl-tRNAIle
This enzyme belongs to the family of
ligases, specifically those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-isoleucine:tRNAIle ligase (AMP-forming). Other names in common use include isoleucyl-tRNA synthetase, isoleucyl-transfer ribonucleate synthetase, isoleucyl-transfer RNA synthetase, isoleucine-transfer RNA ligase, isoleucine-tRNA synthetase, and isoleucine translase. This enzyme participates in valine, leucine and isoleucine biosynthesisand aminoacyl-trna biosynthesis.
As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1FFY, PDB link|1JZQ, PDB link|1JZS, PDB link|1QU2, PDB link|1QU3, PDB link|1UDZ, PDB link|1UE0, PDB link|1WK8, PDB link|1WNY, and PDB link|1WNZ.
CAS registry numberfor this enzyme class is CAS registry|9030-96-0."
