Based on the basic understanding of the interaction shown in Section 2, this section focuses on the system modelling which will be modeled from the viewpoint of active and reactive power flow.
Indeed, PAD2 has similar but non-identical binding pockets in the vicinity of the active site that could be targeted for inhibition, and it is noteworthy that the aminopiperidine benzimidazole scaffold can be modeled to bind the active site of PAD2 in our intermediate structure.
Nonetheless, Cg-Slx1-DNA interactions can be modeled based on the conservation of the active site between Slx1 and GIY-YIG restrictases, for which high-resolution protein-DNA structures are available.
To study the binding mode in the active site of plasmodial ODC and to elucidate binding differences, PPT3 and PPT5 were modeled into the active site of PfODC (Figure 2).
To better understand how the single active site histidine catalyzes isomerization unaided and what the intermediate may be, substrate and product analogues were modeled into the active site of PksEI14.
The most potent first generation inhibitors were modeled into the active site of the M. tuberculosis aldolase structure, with results indicating that the metal chelators tested cannot bind the catalytic zinc in a bidentate fashion while it remains in its catalytic location, and that most enzyme-ligand interactions involve the phosphate binding pocket residues.
Because of the key catalytic functions of this residue, we took great care to confirm that indeed the correct rotamer of Thr168 was modeled at the active site in the uncleaved structure.
Low-energy conformations for alkenes 1– 3 (generated by MM2 molecular mechanics) were overlaid using the enone (C=O, Cα and Cβ) and side chain methylene moieties, then the aggregate was modeled into the active site of wild-type OYE 2.6 in the "flipped" orientation by reference to the experimentally determined position of p-chlorophenol.
To investigate which residue could function as the d-gluconate specific base, d-mannonate and d-gluconate were modeled into the active site of the member from Chromohalobacter salexigens (CsManD) (Uniprot ID Q1QT89) that dehydrates both d-mannonate and d-gluconate (PDB code 3BSM).
We are modeling large-scale conformational changes of subcellular systems active in transcription, assisted folding and motility.
