1 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

5 GO annotations of molecular function

Name Definition
aminoacyl-tRNA editing activity The hydrolysis of an incorrectly aminoacylated tRNA.
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
isoleucine-tRNA ligase activity Catalysis of the reaction: L-isoleucine + ATP + tRNA(Ile) = L-isoleucyl-tRNA(Ile) + AMP + diphosphate + 2 H(+).
tRNA binding Binding to a transfer RNA.
zinc ion binding Binding to a zinc ion (Zn).

1 GO annotations of biological process

Name Definition
isoleucyl-tRNA aminoacylation The process of coupling isoleucine to isoleucyl-tRNA, catalyzed by isoleucyl-tRNA synthetase. The isoleucyl-tRNA synthetase is a class-I synthetase. The activated amino acid is transferred to the 2'-OH group of a isoleucine-accetping tRNA. The 2'-O-aminoacyl-tRNA will ultimately migrate to the 3' position via transesterification.
