All structures in PDB  already have information about their secondary structure content (you can see the attached figure), what other better solutions you are trying to get is not very clear.

Thank you Bipin. But what i am looking for is to compare the results of Circular dichroism results with the PDB results. Unfortunately both are not close to each other

There could be many possible reasons for sec. str. data derived from CD experiment and from X-ray to differ from each other:

1) CD data correspond to solution state, whereas X-ray str. correspond to crystal state, it might possible that the conformation adopted by your system in solution state is different from the crystal state.

2) Accuracy of CD experiment (during spectral measurement and during deconvolution )and its ability to resolve all possible sec str., such as it may not be possible to resolve different types of beta structure present in the protein through CD exp. (such as parallel/antiparallel beta strand and beta turns etc).

It is given at the PDB site under the "sequence" tab. For example see the following:

http://www.rcsb.org/pdb/explore/remediatedSequence.do?structureId=5TT4¶ms.desiredSequenceRnsStr=SEQRES¶ms.showDbRefRulerIfPossible=false¶ms.fontSize=14¶ms.fragmentLength=120¶ms.chainEntityStrategyStr=first

NICE

Hi Bipin Singh do you aware of where the screenshot section you attached moved in the new PDB (https://www.rcsb.org/). I could not be able to locate it under the sequence tab. Can you please help me to find the similar questioned information?

Thanks!

Hi Eswar Reddy Maddi, after the update of PDB I think it is no longer available.

However, you can get the same from PDBSum http://www.ebi.ac.uk/thornton-srv/databases/cgi-bin/pdbsum/GetPage.pl?pdbcode=index.html
