Tailspike protein double mutant D339N/E372Q of E. coli bacteriophage HK620 in complex with hexasaccharide

Enthalpic cost of water removal from a hydrophobic glucose binding cavity on HK620 tailspike protein.

Single amino acid exchange in bacteriophage HK620 tailspike protein results in thousand-fold increase of its oligosaccharide affinity.
