Protein sequence features from sequence inputs?

Hello!

I am currently dealing with some sequence processing and I came to the following problem. I have a bunch of fasta sequences , representing my proteins. How do I find important structural features in such data? I realize this can be done almost exclusively with some database of annotated features, is there any of such kind?

So for example I want to know, how many there are alpha helices, beta strands and so on for each fasta sequence.

Thanks!

Use the InterPro engine as the most informative first pass. 2nd struc prediction not that useful, but gene3D inside InterPro will tell you structure matches with known 2nd struc
