Figure 2

Unliganded MetRS-SLL is in the “met-on” conformation. Top panel: the active site region of unliganded MetRS-SLL (yellow) was superimposed to that of unliganded MetRS (PDB 1QQT; blue). Motions of aromatic residues are indicated by arrows. Bottom panel: same as top panel but unliganded MetRS was replaced by MetRS:Met (PDB 1F4L; blue). The bound methionine is shown in green.
