substrate binding and catalytic mechanisms, overview. Three main pathways are observed most frequently, namely P1, P2A, and P3, evaluation by comparing the average force profiles and potential of mean force calculations revealing that P3 is the unbinding pathway. P1 is located in a tunnel in the beta-propeller domain and contained the D158, R160, S157, S201, A200, S199, W250, D69, Q28, and R287 residues. P2A is located between blades 1 and 2 (G86, E88, K85, H90, D82, and N65), whereas P2D penetrates through blades 1 and 2 formed by loop A, which is close to P2A (S481, F485, D482, L115, I114, R113, H90, E88, R526, and S525). P3 is located between the beta-propeller domain and alpha/beta hydrolase containing the residues M561, A564, L568, F381, T380, I20, A21, F41, K24, G40, G44, and V46 |
