Abstract

A method is presented to draw smooth, 3D ribbon models of proteins. The procedure calculates closely-spaced guide coordinates based on the peptide plane and passes regular, nearly parallel B-spline curves through them. This becomes a simple process with a graphics device having built-in B-spline generating capabilities such as the Evans and Sutherland PS300. Examination of ribbons such as these provides a useful tool for the crystallographer. Any irregularity in the ribbon is a strong visual cue, suggestive of potential problem areas during the refinement process.
