methionine + tRNA(Met) + ATP => Met-tRNA(Met) + AMP + pyrophosphate Authored: D'Eustachio, P, 2008-11-29 15:41:00 EC Number: 6.1.1.10 Edited: D'Eustachio, P, 2008-11-29 15:41:00 MARS2 (mitochondrial methionyl tRNA synthetase) catalyzes the reaction of methionine, mitochondrial tRNA(Met), and ATP to form Met-tRNA(Met), AMP, and pyrophosphate. The enzyme, a class I tRNA synthetase, is a monomer (Spencer et al. 2004).
