FunFam 18900: Cysteine--tRNA ligase
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 7 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the

Aminoacyl-tRNA ligase activity GO:0004812
Catalysis of the formation of aminoacyl-tRNA from ATP, amino acid, and tRNA with the release of diphosphate and AMP.
|
1 | P21888 (/IDA) |
|
Cysteine-tRNA ligase activity GO:0004817
Catalysis of the reaction: ATP + L-cysteine + tRNA(Cys) = AMP + diphosphate + L-cysteinyl-tRNA(Cys).
|
1 | P21888 (/IDA) |
|
ATP binding GO:0005524
Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
|
1 | P21888 (/IPI) |
|
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
|
1 | P21888 (/IDA) |
|
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
|
1 | P21888 (/IPI) |
|
Ligase activity GO:0016874
Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
|
1 | P21888 (/IDA) |
|
Metal ion binding GO:0046872
Interacting selectively and non-covalently with any metal ion.

Cysteinyl-tRNA aminoacylation GO:0006423
The process of coupling cysteine to cysteinyl-tRNA, catalyzed by cysteinyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
