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.

3 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
cysteine-tRNA ligase activity Catalysis of the reaction: ATP + L-cysteine + tRNA(Cys) = AMP + diphosphate + L-cysteinyl-tRNA(Cys).
zinc ion binding Binding to a zinc ion (Zn).

1 GO annotations of biological process

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