Crystal structure of the Sa16Gal30A–Gal2 complex. (a) Ribbon representation of the Sa16Gal30A–Gal2 complex, colored from the N-terminus (blue) to the C-terminus (red). Two bound Gal2 molecules are shown as ball-and-stick models, and subsites −2 and −1 in the catalytic cleft are indicated. The two catalytic residues are shown as magenta stick models. Bound glycerol and MES molecules are shown as stick models. (b) 2Fo − Fc electron-density map of the bound Gal2 molecules in the catalytic domain, contoured at 1.0σ. |
