PROFEAT - Protein Feature Server (2014)

PROFEAT is developed as a web server for computing commonly used features of proteins and peptides from amino acid sequence and of small molecules from molecular structure.

You can choose to calculate feature vector for:

(A)Protein (B)Protein-Protein Interaction Pair

(C)Small Molecule

(D) Protein-Ligand Interaction Pair

For introduction to PROFEAT, please see the Reference Manual


In this page, PROFEAT is designed to compute feature vectrs for protein-ligand interaction (PLI) pairs from protein primary sequence and ligand structures.

upload your data, or try with our sample data

Please upload the

protein sequence, ligand SDF and protein-ligand pair files here:

Upload Proteins


File format of "Upload Proteins" section can be found HERE

Upload Ligand SDF


File format of "Upload Ligand SDF" section can be found HERE
