Crystal structure of species D adenovirus fiber knobs and their sialic acid binding sites.
Adenovirus serotype 37 (Ad37) belongs to species D and can cause epidemic keratoconjunctivitis, whereas the closely related Ad19p does not. Primary cell attachment by adenoviruses is mediated through receptor binding of the knob domain of the fiber protein. The knobs of Ad37 and Ad19p differ at only two positions, Lys240Glu and Asn340Asp. We report the high-resolution crystal structures of the ...
متن کاملSialic acid-binding proteins: characterization, biological function and application.
The last decade has witnessed steadily growing support for the notion that the carbohydrate portion of glycoconjugates is not merely an inert structural addition to the protein or lipid backbone. Considerable attention has been given to the chemical composition of glycosidic residues in such heteropolymers. Sialic acids are frequently occurring components of oligosaccharide side chains in glyco...
متن کاملSialic acid functions in enterovirus 70 binding and infection.
The interaction of viruses with host cell receptors is the initial step in viral infection and is an important determinant of virus host range, tissue tropism, and pathogenesis. The complement regulatory protein decay-accelerating factor (DAF/CD55) is an attachment receptor for enterovirus 70 (EV70), a member of the Picornaviridae, commonly associated with an eye infection in humans known as ac...
متن کاملA Sialic Acid Binding Site in a Human Picornavirus
The picornaviruses coxsackievirus A24 variant (CVA24v) and enterovirus 70 (EV70) cause continued outbreaks and pandemics of acute hemorrhagic conjunctivitis (AHC), a highly contagious eye disease against which neither vaccines nor antiviral drugs are currently available. Moreover, these viruses can cause symptoms in the cornea, upper respiratory tract, and neurological impairments such as acute...
متن کاملRole of sialic acid in bovine sperm-zona pellucida binding.
Sperm binding activity has been detected in zona pellucida (ZP) glycoproteins and it is generally accepted that this activity resides in the carbohydrate moieties. In the present study we aim to identify some of the specific carbohydrate molecules involved in the bovine sperm-ZP interaction. We performed sperm binding competition assays, in vitro fecundation (IVF) in combination with different ...
