Modelling of the GTP binding domain of TgDrpC (A) Monomer model for TgDrpC GTPase domain. The P-loop responsible for tri/diphosphate binding is indicated in yellow, while the switch I region with the putative MG²⁺ coordinating threonine is in blue. (B) close-up of the GDP binding site after molecular dynamics simulation with key residue interacting to the co-substrate shown in ball-and-stick representation, yellow for residues in the P-loop, cyan for residues interacting with the ribose and the guanine.
