Catalytic activity

ATP + L-methionine + tRNA(Met) = AMP + diphosphate + L-methionyl-tRNA(Met). HAMAP-Rule MF_01228

Cofactor

Binds 1 zinc ion per subunit By similarity.

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the class-I aminoacyl-tRNA synthetase family. MetG type 2A subfamily.
