1.5.5.2 - 392565 1.5.5.2 2.15 A resolution structure of the PRODH inactivated by N-propargylglycine. The initial events involved in broadcasting the reduced flavin state to the distal membrane-binding domain include major reorganization of the flavin ribityl chain, severe butterfly bending of the isoalloxazine ring, and disruption of an electrostatic network involving the flavin N(5) atom, Arg431, and Asp370. The active site is incompletely assembled in the absence of the substrate, and the binding of proline draws together conserved residues in helix 8 and the beta1-alphal loop to complete the active site 711252 1.5.5.2 hanging drop method 659987 1.5.5.2 inhibitor thiazolidine-2-carboxylate covalently binds to the N5 of the FAD in the PRODH domain. The modified FAD exhibits a large butterfly bend angle 763802 1.5.5.2 mutant Y540S 696361 1.5.5.2 purified TtProDH mutant variant DELTAABC lacking helices alphaA, alphaB and alphaC, X-ray diffraction structure determination and analysis at 2.2 A resolution 743834 1.5.5.2 sitting-drop vaor diffusion method, structures of the PutA PRODH domain complexed with competitive inhibitors, acetate, L-lactate and L-tetrahydro-2-furoic acid 658033
