Protein attributes

Sequence length340 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

ATP + L-tryptophan + tRNA(Trp) = AMP + diphosphate + L-tryptophyl-tRNA(Trp). HAMAP-Rule MF_00140

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the class-I aminoacyl-tRNA synthetase family.

Sequence caution

The sequence BAC64949.1 differs from that shown. Reason: Erroneous initiation.
