Figure 1
Overall structure of the catalytic domain: SseI (137-322). (a) Overall fold shown as a cartoon diagram. Each of the eight helices (blue) and six [beta]-strands (red) are numbered, with the catalytic triad Cys178, His216 and Asp231 shown as sticks in orange. The missing residues 264-266 are shown as a green line. (b) Topology of the catalytic domain. (c) Secondary-structure alignment with the sequence of the catalytic domain generated by PDBSum (Laskowski, 2009BB20). Helices are numbered with an H and strands with a [beta]. [beta]-Turns are indicated by [beta], [gamma]-turns by [gamma] and [beta]-hairpins by [\supset].  [article HTML]
