Abstract Abstract An algorithm for predicting the structure of a protein, based on a model for protein folding termed folding by hierarchic condensation is presented. The algorithm is applied to a set of six proteins and shown to predict both secondary and super-secondary structures accurately. I ndependently N ucleated U nits of S tructure. The algorithm ascends the folding hierarchy in discrete stages with concomitant accretion of structure at each stage.
Further studies are underway to obtain statistical estimates of the accuracy of the program.
