Figure 2
Overall fold and topology of Ape1. (a, b) Ape1 is represented by a ribbon diagram. The domains are joined by short linker segments coloured yellow. The catalytic domain is coloured light blue and the putative peptidoglycan-binding domain is coloured brick red. In (b) Ape1 is rotated 90°. (c) Structural comparison of the Ape1 N-lobe with XYL-CBM35 and of the Ape1 C-lobe with E. coli thioesterase, a member of the SGNH hydrolase family. PDB codes are included in the labels. (d) Surface model of Ape1. Highly conserved residues in the active site of Ape1 are coloured red. |
