Figure 2.
Fig. 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 ID:
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 ID: 1F4L; blue). The bound methionine
is shown in green.
