Subunits

EC Number Subunits Comment Organism
6.1.1.20 More the separated subunits do not possess any detectable tRNA-amino-acylation activity Thermus thermophilus
6.1.1.20 More the separated subunits do not possess any detectable tRNA-amino-acylation activity Escherichia coli
6.1.1.20 More beta-subunits exist in solution mainly in the monomeric form with negligible formation of beta2-dimers. The alpha-subunits predominantly form alpha2-dimers Escherichia coli
6.1.1.20 More both alpha- and beta-subunits mainly exist in the dimeric form Thermus thermophilus
