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.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
metal ion binding Binding to a metal ion.
threonine-tRNA ligase activity Catalysis of the reaction: ATP + L-threonine + tRNA(Thr) = AMP + diphosphate + L-threonyl-tRNA(Thr).
tRNA binding Binding to a transfer RNA.

1 GO annotations of biological process

Name Definition
threonyl-tRNA aminoacylation The process of coupling threonine to threonyl-tRNA, catalyzed by threonyl-tRNA synthetase. The threonyl-tRNA synthetase is a class-II synthetase. The activated amino acid is transferred to the 3'-OH group of a threonine-accetping tRNA.
