Area of Science:

  • Evolutionary biology
  • Molecular biology
  • Biophysics

Background:

  • Theories of protein evolution are rapidly developing.
  • Understanding early protein evolution requires integrating diverse data.

Purpose of the Study:

  • To review recent advances in protein evolution theory.
  • To outline specific stages of early protein evolution.

Main Methods:

  • Reconstruction of codon chronology.
  • Analysis of protein loop fold structure.
  • Quantitative analysis of DNA ring closure size and protein domain size.

Main Results:

  • Specific stages in early protein evolution can be identified.
  • Each evolutionary stage is characterized by a distinct protein domain size range.

Conclusions:

  • Codon chronology and structural analysis provide insights into protein evolution.
  • Protein domain size is a key indicator of evolutionary stage.
