Subunits

EC Number Subunits Comment Organism
6.1.1.10 monomer MetRs is a monomeric multidomain enzyme, comparisons with other MetRS structures. The MetRS core unit consists of four domains: the catalytic domain, the CP domain, the KMSKS domain, and an anticodon-binding domain.the enzyme crystal structure contains a KMSKS(301-305) loop in proximity to the catalytic site in an open and inactive conformation, overview Mycolicibacterium smegmatis
