Metalloproteins to Membrane Proteins Biological Energy Transduction Mechanisms... 

Metalloproteins and membrane proteins represent extremely broad classifications of proteins with diverse biological roles this article cannot begin to adequately introduce either area, much less both. Instead, one example each of a metalloprotein (nitrogenase) and a membrane protein (MscL) will be described, emphasizing the functional implications of the structural studies, particularly in the context of energy transduction mechanisms. 

Biological membranes define the very existence of cells. They provide compartments for the different components of the living system interact with, transport and are permeable to substrates. They are involved in lipid and protein syntheses, energy transduction, ion and group transport, information transmission and molecular and cellular recognition. These multitude of activities are accomplished by the unique morphology of the biological membrane and by its ability to affect the transport of species by different mechanisms. 

The basic principle in the molecular mechanism of biological photoreceptors appears to be the interaction between a photochromic moiety and a macromolecule. The protein-ligand complex as a whole is known to be embedded in a membrane matrix. In a very general way the results of our studies can be summarized by stating that in photochemical energy transductions both features are very important. That is, the...
