question: Are there any tools that could predict protein structure considering amino acid sequence?
answer: Yes. Tools such as Jpred, Jnet, Porter 4.0 and PSIPRED Workbench have been developed that predict protein structure based solely on its amino acid sequence, whereas the recently updated Jnet algorithm provides a three-state (alpha-helix, beta-strand and coil) prediction of secondary structure at an accuracy of 81.5%.
