Abstract | dc.description.abstract | Based on a similarity ring constructed from a substitution probability matrix, we have analyzed the conservation of some amino acid properties in the evolution of proteins. Refractive index and bulkiness are highly conserved, hydrophobicity and polarity are fairly well conserved while optical rotation appears to be a less relevant property. On the other hand, the analysis of the correspondence between phenotype and genotype shows that the most frequent amino acid substitutions in proteins do not always correspond to the most feasible codon changes. The apparent disagreement between amino acid substitions in modern proteins and the primordial amino acid-codon assignment is discussed. | |
