Welcome to Revenant

Revenant contains a hand-curated collection of 211 resurrected proteins where 55 of them have at least one crystallographic structure. It summarizes a total of 89 crystallized structures of resurrected proteins. All entries in Revenant have been annotated with different information such as: the ancestral node used in the reconstruction, methodologies used for sequence estimation, used sequence alignments, ligand characterization, etc. Several resurrected proteins have additionally, biochemical parameters (i. e. Km, kcat) and thermodynamics parameters characterizing their stability. The oldest Revenant entry corresponds to a reconstruction from ~4200 millions years (MY) and the younger to just ~1.7 MY. All the Revenant proteins are extensively linked with other databases such as PDB, UniProt, Gene Ontology, PubMed and NCBI.

Revenant is created and maintained in a joint effort by the Structural Bioinformatics Group - National University of Quilmes (SBG-UNQ) and the Group of Artificial Intelligence - Pontifical Catholic University of Peru (IA-PUCP) Read more.
