MBC

Sequences of Chloroflexota bacterium origin with tagatose-4-epimerase activity

We calculated the binding free energy of the receptor-ligand complexes using the CHARMm-based energy function and an implicit solvent model. The binding energy between the receptor and ligand (ΔEBinding) is defined as EComplex = ELigand - EReceptor. To estimate these free energies, we minimized the ligand energy in the presence of the receptor using the steepest descent and conjugate gradient methods. The effective Born radii were computed using the Generalized Born Simple Switching (GBSW) implicit solvent model, replacing the costly molecular surface approximation with a smooth dielectric boundary combined with a van der Waals surface. Using this approach, we calculated the binding free energy between the MBC sequences and fructose(Fig. 1).


Fig. 1 Binding free energy between the MBC sequence and fructose (using the final selected sequence as an example)

From Figure 1, the free energy of docking between MBC and fructose is -7.2569kcal/mol. Sequence and Features
