We started DSSP on the webserver with the PDBB-id. Therefore, we get the secondary structure assignment for the whole protein and not only for the alpha-subunit. The following sequence with the according secondary structure is the output for our sequence (we extracted it from the whole). It assigned 16 alpha-helices and no beta-sheet.

PSIPRED

PSIPRED delivers many different kind of output file formats. The pictures show the pdf-output which shows the secondary structure in a graphical kind. It predicts 14 alpha-helices and 15 beta-sheets. The rest are predicted coils.

Jpred3

The following alignemt shows the output of Jpred3. The secondary structure elements is marked by ourself. It predicted 14 alpha-helices and 15 beta-sheets.

DSSP

We started DSSP on the webserver with the PDBB-id. Therefore, we get the secondary structure assignment for the whole protein and not only for the alpha-subunit. The following sequence with the according secondary structure is the output for our sequence (we extracted it from the whole). It assigned 16 alpha-helices and no beta-sheet.
