Variability of three-dimensional structure in immunoglobulins.
A comparison of various variable immunoglobulin domains demonstrates that structural variability parallels the observed frequency of amino-acid substitutions. The similarity of the structural frameworks is in good agreement with the evolutionary relationships of the chains as derived from sequence analysis.
