Abstract
Using, in part, comparisons between reconstructed ancestral sequences, homologies are suggested between certain proteins. Genetically related groups seem to be: 1. pancreatic and bacterial nucleases, 2. lysozymes and subtilisins, 3. c type cytochromes, ferredoxins and rubredoxins, 4. b type cytochromes, myoglobins and hemoglobins, catalase, and glutamic dehydrogenase. These homologies suggest that a given ancestral sequence can evolve into quite different tertiary structures.Keywords
