Physiological function design requirements

Perhaps as more is learned about the molecular requirements for binding therapeutic agents to active sites of macromolecules as part of the intention to control physiological function, these simple transport requirements can be incorporated into the molecular design. 

There are several requirements for an "ideal protein system for such studies [68-70]. First, in order to facilitate structure vs. function comparisons, the proteins studied should be of known structure. This structure may be obtained, for example, by high-resolution X-ray spectroscopy. Second, physiological redox protein couples are preferred, since such systems are more likely to provide information on biological design than studies of non-physiological redox couples. Third, for practical purposes, it is...
