Phycodnaviruses: a peek at genetic diversity.

The family Phycodnaviridae encompasses a diverse collection of large icosahedral, dsDNA viruses infecting algae. These viruses have genomes ranging from 160 to 560kb. The family consists of six genera based initially on host range and supported by sequence comparisons. The family is monophyletic with branches for each genus, but the phycodnaviruses have evolutionary roots that connect with seve...

A peek at ice binding by antifreeze proteins.

W hat is the toughest recognition problem in biology? Arguably, it is that faced by antifreeze or thermal hysteresis proteins. These proteins provide a broad range of organisms with protection against freezing damage by depressing, in a noncolligative manner, the freezing point of water. They do this by binding to nascent ice nuclei and inhibiting their growth (1). In other words, antifreeze pr...
