Cover illustration: A Chi60 chitinase molecule (p. 821) attached to the surface of chitin via its chitin-binding domain. The structure of Chi60 is crystallographic. The surface of chitin has been generated by expanding the known crystal structure of an N-acetyl glucosamine oligomer by the application of crystallographic symmetry. The association of Chi60 with the chitin surface is hypothetical. The inset shows the three surface tryptophan side chains of the chitin-binding domain in their hypothetical interaction with the chitin surface.
