Predicting protein 3D structure from sequence remains a challenge. New computational methods and growing databases are improving predictions, narrowing the gap between known sequences and structures.

Area of Science:

  • * Computational biology and bioinformatics.
  • * Structural bioinformatics and protein structure prediction.

Background:

  • * Accurately predicting protein three-dimensional (3D) structure from amino acid sequence is a fundamental unsolved problem in biology.
  • * Existing methods like homology modeling and threading can predict structures for a portion of proteins, but limitations remain.

Purpose of the Study:

  • * To review recent advancements in protein structure prediction methods.
  • * To highlight the impact of computational tools and large-scale databases on improving prediction accuracy.

Main Methods:

  • * Discusses homology modeling for predicting structures based on known templates.
  • * Explains threading methods for detecting remote similarities and fitting sequences into known folds.
  • * Reviews 1D prediction tools for secondary structure, solvent accessibility, and transmembrane helices.
