Sequence Similarity Search

Search protein structures by amino acid sequence similarity (BLAST). Input a protein sequence and find all PDB structures with matching chains. Configure identity cutoff (e.g. 90%) and E-value threshold. Returns PDB entity IDs ranked by similarity score. Essential for homology modeling and structure prediction (RCSB PDB)
