In
enzymology, an isoleucine—tRNA ligase (EC 6.1.1.5) is an enzyme that catalyzes the chemical reaction
- ATP + L-isoleucine + tRNAIle AMP + diphosphate + L-isoleucyl-tRNAIle
The 3
diphosphate, and L-isoleucyl-tRNA(Ile)
.
This enzyme belongs to the family of
valine, leucine and isoleucine biosynthesis and aminoacyl-trna biosynthesis
.
Structural studies
As of late 2007, 10
structures have been solved for this class of enzymes, with PDB accession codes 1FFY, 1JZQ, 1JZS, 1QU2, 1QU3, 1UDZ, 1UE0, 1WK8, 1WNY, and 1WNZ
