Web11 apr. 2006 · The analysis shows that selection involving even eight converging contacts can be reliably detected. To put these results in context, each of the six hemoglobin helices contains about 16 contact characters. Convergent positioning of half of the contacts of a single helix in a single pair of structures might be detected by this method. WebThe α-helix is a regularly repeated polypeptide backbone structural motif that can be identified to varying degrees in the folded 3-D conformations of most proteins.

WebThe hemes are pigments that endow hemoglobin with its bright red color and its ability to bind and release oxygen. Each heme consists of a central iron atom held in an aromatic, porphyrin ring. The iron is ionized ( Fe+++ when O2 is bound and Fe++ when O2 has been released). The iron is coordinated by four nitrogen atoms in the center of the ring.
