Ordered surface carbons distinguish antifreeze proteins and their ice-binding regions

Antifreeze proteins (AFPs) are found in cold-adapted organisms and have the unusual ability to bind to and inhibit the growth of ice crystals. However, the underlying molecular basis of their ice-binding activity is unclear because of the difficulty of studying the AFP-ice interaction directly and the lack of a common motif, domain or fold among different AFPs. We have formulated a generic ice-binding model and incorporated it into a …
