the initial studies have focused on understanding the binding of these heavy metals to peptides. arsenic (as), mercury (hg), and cadmium (cd) all were used in systems with various peptides. arsenic was found to bind to peptides via primarily a trigonal-pyramidal or tetrahedral shape in a manner that is both kinetically and thermodynamically favorable. mercury on the other hand was found to bind to two sulfur atoms in separate peptides via a linear shape, thus causing the formation of a two strand coiled coil. it was also shown that under certain conditions, termed stepwise aggregation-deprotonation, mercury can be made to bind three sulfurs thus yielding a three strand coiled coil with an hg in the middle. cadmium was the last heavy metal studied in these systems. it was found that cd also binds to three separate sulfurs, though it does not resemble the hg system in that it does not form a linear binding shape within a two strand coiled coil. this information obtained gives valuable information on how these heavy metals interfere with proteins and their folding. this is the first step in understanding and potentially, solving heavy metal binding in the body.
