Function
function
Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
Catalytic activity
- tRNA(Met) + L-methionine + ATP = L-methionyl-tRNA(Met) + AMP + diphosphate
Cofactor
Note: Binds 1 zinc ion per subunit.
