| Predicting protein structure using hidden Markov models (1997) | |||||||||||||||||
Abstract | |||||||||||||||||
| We discuss how methods based on hidden Markov models performed in the fold-recognition section of the CASP2 experiment. Hidden Markov models were built for a representative set of just over one thousand structures from the Protein Data Bank (pdb). Each CASP2 target sequence was scored against this library of hmms. In addition, an hmm was built for each of the target sequences, and all of the sequences in pdb were scored against that target model, with a good score on both methods indicating a high probability that the target sequence is homologous to the structure. The method worked well in comparison to other methods used at CASP2 for targets of moderate difficulty, where the closest structure in pdb could be aligned to the target with at least 15% residue identity. y To whom correspondence should be addressed.
