How can I obtain the PDB ID for a protein from a Genbank flat file? I want to use PdbEfold for a putative ankyrin repeat protein (Accession #: ANB50278) from a Megavirus genome and I need the PDB ID in order to do the search, or to do other searches to find structurally-related genes (such as VAST or DALI).
I have the GenBank flat file with the protein accession number and the FASTA sequence for the protein, but when I searched the PDB Databank I found no results for this protein. I also tried performing a BLAST search against the PDB database with no luck. Is it possible that the protein does not have a PDB ID? And if it is possible, is there a way to use PdbEfold, VAST or DALI for my protein without the PDB ID? If you can't already tell, I am a bit of an amateur in this field and would appreciate any help!!
