Figure 4
Different conformations of loop 250–255 in the crystal structures of choline oxidase in complex with glycine betaine and with DMSO (PDB entry 2jbv ). (a) The superimposed structures are shown as a light gray cartoon for choline oxidase in complex with glycine betaine and as a dark gray cartoon for choline oxidase in complex with DMSO (PDB entry 2jbv ). The FAD cofactor of choline oxidase in complex with glycine betaine is shown in yellow sticks; the conformations of the main chains of loop 250–255 are highlighted in red for choline oxidase in complex with DMSO (PDB entry 2jbv ) and in blue for choline oxidase in complex with glycine betaine. For clarity, only loop 250–255 of subunit B is shown. (b) The main chain of the residues of loop 250–255 and the side chain of Phe253 of choline oxidase with glycine betaine are shown as blue sticks and the electron density of the OMIT map is shown in blue (contoured at 0.5 e Å−3) and in gray (contoured at 0.33 e Å−3); the same atoms in the structure with DMSO (PDB entry 2jbv ) are shown as red sticks. |
