[6] 76% of predictions achieved better than 3 Å, and 46% had a C-alpha atom RMS accuracy better than 2 Å, [6] with a median RMS deviation in its predictions of 2.1 Å for a set of overlapped CA atoms. [6] AlphaFold 2 also achieved an accuracy in modelling surface side chains described as "really really extraordinary".
In molecular biology, protein fold classes are broad categories of protein tertiary structure topology. They describe groups of proteins that share similar amino acid and secondary structure proportions. Each class contains multiple, independent protein superfamilies (i.e. are not necessarily evolutionarily related to one another). [1] [2] [3]
The goal of protein design is to find a protein sequence that will fold to a target structure. A protein design algorithm must, thus, search all the conformations of each sequence, with respect to the target fold, and rank sequences according to the lowest-energy conformation of each one, as determined by the protein design energy function.
Protein before and after folding Results of protein folding. Protein folding is the physical process by which a protein, after synthesis by a ribosome as a linear chain of amino acids, changes from an unstable random coil into a more ordered three-dimensional structure.
Most proteins fold into unique 3D structures. The shape into which a protein naturally folds is known as its native conformation. [36]: 36 Although many proteins can fold unassisted, simply through the chemical properties of their amino acids, others require the aid of molecular chaperones to fold into their native states.
The alpha/beta hydrolase superfamily is a superfamily of hydrolytic enzymes of widely differing phylogenetic origin and catalytic function that share a common fold. [1] The core of each enzyme is an alpha/beta-sheet (rather than a barrel ), containing 8 beta strands connected by 6 alpha helices .

A leucine-rich repeat (LRR) is a protein structural motif that forms an α/β horseshoe fold. [1] [2] It is composed of repeating 20–30 amino acid stretches that are unusually rich in the hydrophobic amino acid leucine. These tandem repeats commonly fold together to form a solenoid protein domain, termed leucine-rich repeat domain.
