Circular dichroism curves of poly-L-lysine con-taining varying amounts of a helix,/3-
pleatedsheet, and random coil segments have been computed in the 190-250-µ region. The
application of these curves for determining protein conformation is discussed. The circular
dichroism curves of several proteins, whose three-dimensional structures are known from X-
ray diffraction studies, have been fitted by a linear combination of the threereference
structures in the 208-240-µ region. Theresults show that these computed
