Abstract

An Applesoft BASIC program is presented which allows one to readily graph the secondary structure of a protein on the basis of information derived from its amino acid sequence. This applies the Chou/Fasman rules of predictions to the α-helix, β-sheet and coil conformational parameters. The program produces a first approximation and provides the additional feature which permits specific modification in the plotted structure. These modifications produce a plot comparable to the existing data obtained from X-ray crystallography and manual computations. © 1982.
