Abstract

Glutamine-Binding Protein (GlnBP) from Escherichia coli is an extremely important periplasmic binding protein. Binding of glutamine at the cleft between two domains causes a conformational change corresponding to a closure of two domains around the ligand. Because this process has a close relationship with protein function, studying this process has an important biological significance. It is very difficult for the existing experimental methods to obtain the conformational transition of GlnBP. In this paper, we studied the allosteric mechanism of GlnBP by using the adaptive Anisotropic Network Model (aANM) proposed by Bahar and obtained a relatively reasonable allosteric pathway. This work is helpful for the understanding the role of the topology structure in GlnBP conformational transition.
