Why is it difficult to solve a protein folding problem?

In part, it is because protein folding is a kinetics driven process, and not one that necessarily reaches minimum free energy. As such, one has to model the environment quite well and this is harder than just looking at interactions among the residues along the sequence.

Can Protein Folding be predicted?

Deep-learning algorithms such as AlphaFold2 and RoseTTAFold can now predict a protein’s 3D shape from its linear sequence — a huge boon to structural biologists.

Is protein folding an NP problem?

Protein folding problem is a Non deterministic Polynomial hard problem. Proteins are of different types, whereas each protein plays an important role in the living cells. Every protein has a unique structure and function. The unique structure is formed by folding of proteins from sequence of amino acids.

Is protein folding problem solved?

DeepMind’s protein-folding AI has solved a 50-year-old grand challenge of biology. AlphaFold can predict the shape of proteins to within the width of an atom. The breakthrough will help scientists design drugs and understand disease.

Why correct protein folding is important in the structure of protein?

Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases.

Why is protein folding prediction important?

Protein folding The shape determines its function. If the structure of the protein changes, it is unable to perform its function. Correctly predicting protein folds based on the amino acid sequence could revolutionize drug design, and explain the causes of new and old diseases.

What determines protein folding?

Protein folding is a very sensitive process that is influenced by several external factors including electric and magnetic fields, temperature, pH, chemicals, space limitation and molecular crowding. These factors influence the ability of proteins to fold into their correct functional forms.
