[Baylor College of Medicine] A secondary structure prediction tool.
BCM Search Launcher: Protein Secondary Structure Prediction
[Baylor College of Medicine] This site allows the selection of any of several secondary structure prediction tools to analyse a protein sequence.
[EMBnet - Swiss Node] "COILS is a program that compares a sequence to a database of known parallel two-stranded coiled-coils and derives a similarity score. By comparing this score to the distribution of scores in globular and coiled-coil proteins, the program then calculates the probability that the sequence will adopt a coiled-coil conformation."
Computational Services at EMBL
[EMBL] Ties together sequence search and retrieval, alignment, data submission, comparison and prediction into one site. Also available are tools for structure verification and related software.

[SWBIC] Protein Classification through the Assessment of Predicted Secondary Structure (PCAPSS) is a method for identifying remote protein homologs in the Protein Data Bank that share a similar secondary
structure to the query protein. PCAPSS was designed to be used with orphan or hypothetical proteins, i.e.,
those for which amino acid sequence searches fail to find similar sequences with functional annotation. Its purpose
is to generate hypotheses for structure and function for such hypothetical or putative protein sequences based on

Protein Structure Prediction Center and CASP
[Lawrence Livermore National Laboratory] "Our goal is to help advance the methods of identifying protein structure from sequence. The Center has been organized to provide the means of objective testing of these methods via the process of blind prediction. In addition to the support of the CASP meetings our goal is to promote an objective evaluation of prediction methods on a continuing basis." CASP stands for Critical Assessment of techniques for protein Structure Prediction.
