Aggrecanase-2 (a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5)), a member of the ADAMTS protein family, is critically involved in arthritic diseases because of its direct role in cleaving the cartilage component aggrecan. The catalytic domain of aggrecanase-2 has been refolded, purified, and crystallized, and its three-dimensional structure determined to 1.4Å resolution in the presence of an inhibitor. A high resolution structure of an ADAMTS/aggrecanase protein provides an opportunity for the development of therapeutics to treat osteoarthritis.

The technique of freeze-etching is illustrated with reference to striated muscle. Besides features of immediate biological interest, the material demonstrates various ways in which the process may be used in general to yield new information. These fall broadly into two classes: ( a ) qualitative: visualizing structures not readily seen by other methods, for example, general three-dimensional structure (low resolution) and membrane particles (high resolution); ( b ) quantitative, for example, the distribution of membrane features over extensive uneven surfaces (low and high resolution).
