Aconitase is an unusual example of one of these that interacts directly with its substrate.
Aconitase is an unusual example of one of these that interacts directly with its substrate. In Rieske proteins, the central structure is coordinated with histidine residues, rather than with cysteine. Nitrogenases have a variant structure of this type which includes a metallic heteroatom such as molybdenum or vanadium. In one configuration of them, their namesake atoms are arranged at the vertices of a cube. Their ubiquity has led to the hypothesis by WÃ¤chtershÃ¤user that their two core elements were an essential part of the development of early life on earth. They include the ferredoxins, and mostly play roles as electron carriers. For 10 points, name this class of proteins distinguished by the presence of a cluster of two particular elements.
