The leghemoglobin proximal heme pocket directs oxygen dissociation and stabilizes bound heme.

Proteins - 15 Feb 2002

Abstract excerpt

Sperm whale myoglobin (Mb) and soybean leghemoglobin (Lba) are two small, monomeric hemoglobins that share a common globin fold but differ widely in many other aspects. Lba has a much higher affinity for most ligands, and the two proteins use different distal and proximal heme pocket regulatory mechanisms to control ligand binding. Removal of the constraint provided by covalent attachment of the proximal...
