motions, of up to approximately 4.5 Å, are most pronounced in the region of the GH loop.<br />

In contrast, HRV1A and HRV16, a minor and major receptor group virus respectively, have their<br />

pockets in open conformations even in the absence of drug [13,15]. For these serotypes, drug binding<br />

typically shifts positions of capsid atoms a maximum of 1 to 2 Å, smaller than those shifts seen in<br />

HRV14. <strong>Drug</strong>s bind in these pockets in a fashion similar to that seen in HRV14, extended and almost<br />

entirely buried <strong>by</strong> VP1.<br />

The structures of five HRVs have been solved to date: HRVs 1A, 3, 14, 16, and 50. In all of these<br />

HRVs, as well as the polio- and coxsackie viruses, VP1 hydrophobic pockets have been observed<br />
