		+	== Publication Abstract from PubMed ==
		+	A springtail (Collembola) identified as Granisotoma rainieri was collected from snow in Hokkaido, Japan in late winter when nighttime temperatures were below zero. Extracts of these arthropods showed antifreeze activity by shaping ice crystals and stopping their growth. The glycine-rich proteins responsible for this freezing point depression were isolated by ice-affinity purification and had principal masses of ~6.9 and 9.6 kDa. We identified a transcript for a 9.6-kDa component and produced it as a His-tagged recombinant protein for structural analysis. Its crystal structure was solved to a resolution of 1.21 A and revealed a polyproline type II helical bundle, similar to the six-helix Hypogastrura harveyi AFP, but with nine helices organized into two layers held together by an extensive network of hydrogen bonds. One of the layers is flat, regular, and hydrophobic and likely serves as the ice-binding side. Although this surface makes close protein-protein contacts with its symmetry mate in the crystal, it has bound chains of waters present that resemble those on the basal and primary prisms planes of ice. Molecular dynamics simulations indicate most of these crystal waters would preferentially occupy these sites if exposed to bulk solvent in the absence of the symmetry mate. These pre-positioned waters lend further support to the ice-binding mechanism in which AFPs organize ice-like waters on one surface to adsorb to ice.
