Maltodextrin Binding Protein

Explore the structure, interactions, and function of Maltodextrin Binding Protein (MBP), an integral membrane protein involved in maltose transport and chemotaxis system in E. coli. Learn about its topology, hydrogen bonding, van der Waals interactions, structural plasticity, specificity, and sites interacting with membrane transport and chemotaxis.
