FunctionHemagglutinin-esterase (HE) is a glycoprotein of the envelopes of some viruses. HE recognizes the host cell surface receptor - a sialic acid derivative. The esterase region of the HE is responsible for the destruction of the receptor[1]. Structural highlightsThe biological assmebly of HE is a and each monomer contains . The receptor binding site of HE is located at five exposed surface loops. . HE contains a [2]. 3D structures of hemagglutinin-esteraseHemagglutinin-esterase 3D structures
