3D Structural Insights into ?-Glucans and Their Binding Proteins.


ABSTRACT: ?(1,3)-glucans are a component of fungal and plant cell walls. The ?-glucan of pathogens is recognized as a non-self-component in the host defense system. Long ?-glucan chains are capable of forming a triple helix structure, and the tertiary structure may profoundly affect the interaction with ?-glucan-binding proteins. Although the atomic details of ?-glucan binding and signaling of cognate receptors remain mostly unclear, X-ray crystallography and NMR analyses have revealed some aspects of ?-glucan structure and interaction. Here, we will review three-dimensional (3D) structural characteristics of ?-glucans and the modes of interaction with ?-glucan-binding proteins.
