One ofthe major drivers in biological research is the establishment
ofstructures and functions of the 50,000 or so proteins in our
bodies. Each has a characteristic- dimensional structure, highly
"ordered" yet "disordered"! This structure is essential for a
protein's function and, significantly, it must be sustained in the
competitive and complex environment of the living cell. It is now
being recognised that when a cell loses control, proteins can se-
assemble into more complex supermolecular structures such as the
amyloid fibres and plaques associated with the pathogenesis of
prion (CJD) or age-related (Alzheimer's) diseases. This is a
pointer to the wider significance of the self-assembling properties
of polypeptides. It has been long known that, in silk, polypeptides
are assembled into- sheet structures which impart on the material
its highly exploitable properties of flexibility combined with high
tensile strength. But only now emerging is the recognition that
peptides can Self-assemble into a wide variety of non-protein-like
structures, including fibrils, fibres, tubules, sheets and
monolayers. These are exciting observations and, more so, the
potential for materials and medical exploitations is so wide
ranging that over 80 scientists from Europe, USA, Japan and Israel.
met 1-6 July 1999 in Crete, to discuss the wide-ranging
implications of these novel developments. There was a spirit of
excitement about the workshop indicative of an important new
endeavor. The emerging perception is that of a new class of
materials set to become commercially viable early in the 21st
century.
