Overall structure of recombinant EG27II. (a) A ribbon model of the apo form of EG27II. α-Helices, 310-helices and β-strands are shown in red, orange and blue, respectively. Catalytic residues are shown in yellow. (b) Topology diagram of EG27II. Red boxes, orange boxes and light blue arrows represent α-helices, 310-helices and β-strands, respectively. (c) The overall structures and the amino-acid residues around the catalytic cleft of EG27II under different pH conditions. The structures at pH 4.0, 5.5 and 8.0 are colored yellow, green and purple, respectively. |
