The allowed regions

on the plot represent the regions in which protein structures are most likely to
be found

The energy minimization
process minimizes the energy of the structures by adjusting the positions of
the atoms in the structures
...
The Ramachandran plots provide insight
into the conformational preferences of amino acids and the relationships
between amino acid sequence and structure
...
The energy function is also used to calculate the
score based on the structure
...

Protein threading is a technique used for creating protein structures or
binding proteins together
...
Essentially,
protein threading is a method used for binding proteins together into a
specific structure
...
While it can be a complex process, the use of energy
functions and the protein data bank make it possible to achieve reliable
results
...

There are often errors and limitations in both the energy functions and data
used, which can impact the end result
...


Protein secondary structure

Proteins consist of secondary structures such as beta sheets and alpha helices
...
The alpha helix and beta strand together also constitute a beta

strand
...
Both beta
sheets and beta strands can be considered as beta helices
...

The protein also has 60 amino acids, and the backbone dihedral angles relate
to the amino acid's acid structure

The Euclidean distance is a measure of distance in Euclidean space
...




An angle can be represented as a vector
...




The dihedral angle between four atoms is a measure of the torsion of three
intersecting planes
...




Degeneracy refers to the number of planes that intersect at a particular
point or line
