PhyloBot

PhyloBot performs automated phylogenetic inference and ancestral sequence reconstruction to infer ancestral protein sequences and identify evolutionary amino acid changes.


Key Features:

  • Automated ancestral sequence reconstruction: Performs phylogenetic ancestral sequence reconstruction to infer ancestral protein sequences.
  • Identification of amino acid changes: Detects and reports key amino acid substitutions across evolutionary timescales.
  • Ordering evolutionary events: Facilitates ordering of historical events related to the evolution of protein functions.
  • Mutational trajectory exploration: Provides interactive computational tools to explore mutational trajectories and evolutionary pathways.
  • Ancestral sequence outputs for synthesis: Produces ancestral sequences suitable for synthesis and experimental comparison with extant proteins.
  • Software integration: Integrates the software components required for ancestral sequence reconstruction and phylogenetic analysis.
  • Implementation and infrastructure: Implemented in Python within the Django web framework and runs on Amazon Web Services elastic cloud computing resources.

Scientific Applications:

  • Experimental resurrection of proteins: Enables reconstruction of ancestral sequences for synthesis and experimental comparison with modern proteins.
  • Functional evolution analysis: Identifies genetic changes that underlie functional shifts in proteins.
  • Hypothesis generation for experimental testing: Generates hypotheses about evolutionary trajectories that can be tested by genetic or biochemical methods.
  • Protein-family studies: Applied to investigate the evolution and mechanisms of protein families such as V-ATPase ion pumps, DNA-binding transcription regulators, and serine/threonine protein kinases.

Methodology:

Performs phylogenetic ancestral sequence reconstruction, identifies amino acid substitutions, and orders historical functional events; implemented in Python with the Django web framework and executed on Amazon Web Services elastic cloud computing resources.
