Folding found on The Greek island of Crete is on a very tectonically active site in the Mediterranean, the subduction zone where the African plate is pushed under the European.

Washington University scientists map key malaria protein -- "The idea is that if we know a protein's structure, it will be easier to design chemicals that would target the protein's active site and shut it down."  Very cool.

Heme, the non-protein active site within myoglobin and hemoglobin. The side-groups which have been added to porphine are highlighted in magenta, and the central iron atom is shown in red. Although the hemoglobin and myoglobin molecules are very large, complex proteins, the active site is actually a non-protein group called heme. The heme consists of a flat organic ring surrounding an iron atom. The organic part is a porphyrin ring based on porphin (a tetrapyrrole ring)...
