Figure 2
Crystal structure of TtGuaA. (a) Ribbon diagram of the TtGuaA homodimer in complex with XMP. Subunit A is shown in blue and subunit B in red. (b) The TtGuaA monomer in complex with XMP (TtGuaA–XMP). The N-terminal glutamine amidotransferase (GATase) domain (residues 1–188) is shown in gray, the ATP pyrophosphatase (ATPPase) domain (residues 189–390) in blue and the C-terminal dimerization domain (residues 391–503) in orange. The two disordered regions 324–339 and 433–444, labeled D1 and D2, respectively, are indicated by red arrows. The P-loop (217–222), labeled PL, is indicated by a black arrow. (c) Schematic drawing of the secondary structure of subunit A of TtGuaA–XMP. The meanings of the colors are the same as in (b). The disordered regions D1 and D2 are indicated by dashed lines and red arrows, respectively. The P-loop, labeled PL, is indicated by a black arrow. (d) Superposition of the TtGuaA proteins. The apo form of TtGuaA is shown in tan and TtGuaA–XMP in shown in cyan. |
