The Divergence of Halophilic Superoxide Dismutase Gene Sequences: Molecular Adaptation to High Salt Environments

  • Patrick P. Dennis

Abstract

During the divergence of homologous sequences, nucleotide substitutions can become fixed either through random processes or by virtue of positive selection.6,9,14 The underlying components that together contribute to a positive selection value for a given substitution can be many and varied. They could include selection (i) for altered structure or function within the encoded protein, (ii) for codon utilization as it relates to either efficiency or accuracy of mRNA translation, and (iii) for regulatory signals or secondary structure embedded in the DNA or mRNA sequence.
