secondary structure

To predict secondary structure we use the following tools and compare the results: 

-reprof
-psipred
-DSSP_Server

Methods

reprof

to run reprof from the command line the following command is used: 

reprof -i seq.fasta

reprof then calculates the secondary structure prediction and provides an output file "seq.reprof". Reprof can be run with a single fasta file, or with a BLAST/HHBlits - PSSM file. We have tried both variants, because the second variant promises more accurate results. We used HHBlits - PSSM files for this purpouse. Result: (H = Helix, E = Extended/Sheet, L = Loop)

reprof with fasta

reprof with HHBlits - PSSM (up20)

To retrieve PSSM-files from hhblits, the tool hhblits_pssm.pl from the hhsuite is used( we used the version installed in "/opt/hhblits/hhblits/" on jobtest ). It is started from the command line with the following command: 

hhblits_pssm.pl --infile query.fasta --outfile query.pssm -h "/mnt/project/rost_db/data/hhblits/uniprot20_current"

now reprof is run using the created pssm's. Results:

DSSP_Server

to use DSSP_Server we first had to determine which pdb-ID's are associated with the uniprot ID's P12694, P10775, Q9X0E6, Q08209

This table shows the result of our comparison. Psipred performs on all targets way better than reprof using a single fasta file, but reprof outperforms psipred in 3/4 cases using a HHBlits PSSM as query, in case 4 they perform even. The TruePositives( TP's ) represent the matched secondary structure elements between the predicted method and DSSP in the range of the DSSP file.

Disorder

To predict Disorder in our Protein obda_human IUPred is used, and compared to the entries in DisProt. As in DisProt only the Protein Q08209 can be found directly, the feature "search by sequence" has to be used and checked wheather reliable hits can be found. The following entries were chosen:

Transmembrane helices

For the prediction of Transmembrane helices in our Protein we used PolyPhobius. In addition to our protein of interest (ODBA_HUMAN, see Reference sequence (uniprot)) we applied the method as well to P35462(D(3) dopamine receptor), Q9YDF8(Voltage-gated potassium channel) and P477863(Aquaporin-4).

Polyphobius predicts ODBA_HUMAN to be a completly cytosomal protein without any transmembrane regions.

P35462 on the other hand is predicted to be a transmembrane protein with seven transmembrane regions.

7.transmembrane 367 386 367 388 363 386 368 382

As can be seen in the table above, the number of transmembrane regions is the same of all three databases and for the prediction. While the transmembrane regions largely overlap between the different information sources, there are some differences regarding the exact start and stop positions of the transmembrane regions. Depending on which Database we choose as standard of truth we get slightly different results for evaluating the performance of the transmembrane region prediction.

Database True Positives False Positives True Negatives False Negatives
UniProt 149 5 2
OPM 141 7+1+3 2

For Q9YDF8 PolyPhobius again predicts seven transmembrane regions.

6.transmembrane 196 213 *196 *208
7.transmembrane 224 244 222 253

In this case however the number of transmembrane regions found per database varies greatly. While Uniprot notes six transmembrane regieons and one intermembrane region (marked with *) that mostly overlap the prediction of Polyphobius, the 1orq structure of the protein has four identical subunits that all have the same three transmembrane regions. According so PDBTM there are four transmembrane regions and one intermembrane region for each of the identical subunits.
