ADENOVIRUS AD19P FIBRE HEAD IN COMPLEX WITH SIALYL-LACTOSE
OverviewOverview
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 Ad37 and Ad19p knobs, both, native and in complex with sialic acid, which has been proposed as a, receptor for Ad37. Overall, the Ad37 and Ad19p knobs are very similar to, previously reported knob structures, especially to that of Ad5, which, binds the coxsackievirus-adenovirus receptor (CAR). Ad37 and Ad19p knobs, are structurally identical with the exception of the changed side chains, and ... [(full description)]
