PDB-2-PB[1,2] is a curated online Protein Block (PB) sequence database. Here, we encoded and provide the PB sequences for all the protein structures available in PDB using de Brevern, encoding procedure. From our PDB-2-PB, users can extract the PB sequences along with their corresponding information as follows; (i) amino acid sequence, (ii) chain length, (iii) sequence start and end positions, (iv) resolution (only for X-ray solved entries), (v) experimental method used, and (vi) dihedral angles (φ and ψ), which we used to assign PB letters.
Description of PB.
Details for PB letters a to p, are available here. For more details about PBs, click here
Detailed statistics for all the versions of PDB-2-PB is available here.

Protein block sequences have many applications in protein structure analysis. Our PB based protein fold recognition server PredictFold-PB can also accessible here.
