This study reviews protein classification systems, advocating for a unified, natural approach. Further comparative analysis is needed to understand protein folds and their cellular functions.

Area of Science:

  • Proteomics
  • Structural Biology
  • Bioinformatics

Background:

  • The protein universe is vast, with numerous structural and functional classification schemes.
  • Existing schemes vary in their features and inter-relationships, leading to potential inconsistencies.

Purpose of the Study:

  • To provide an overview of current protein classification schemes.
  • To propose a unified classification approach based on natural classification principles.
  • To highlight the need for comparative analyses of existing schemes.

Main Methods:

  • Review and analysis of existing protein classification systems.
  • Comparative analysis of structural and functional classification features.
  • Literature synthesis on protein fold and function delimitation.

Main Results:

  • Current classification schemes offer diverse perspectives but lack a unified framework.
  • A natural classification approach is proposed as a basis for a unified scheme.
  • Understanding limitations and inter-relationships of current schemes is crucial.

Conclusions:

  • A unified protein classification system is necessary for a comprehensive understanding of the protein universe.
  • Further comparative studies are essential to refine classification schemes.
  • Delimiting protein folds and their functions requires a standardized classification approach.
