Correlated Flexible Molecular Coding and Molecular Evolvability

Evolvability of biopolymers is based on molecular coding. The molecular coding is represented by biopolymer function vs monomeric sequence relationship, that is, a proper fitness landscape on the sequence space. On the other hand, molecular coding is mostly realized by monomeric sequence vs biopolymer structure relationship. We suggest the evolution of evolvability based on flexible or multiplex coding originating from flexible or polymorphic conformation of evolving biopolymers. We report a finding supporting that the amino acid landscape of the standard genetic code for an amino acid property which is more important to the protein function gives higher value of an evolvability measure. We developed a promising molecular construct which realized genotype-phenotype linking in order to study the in vitroprotein evolution to clarify above mentioned protein evolvability.
