Allosteric regulation
In biochemistry, allosteric regulation (or allosteric control) is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site.

Amino acid
Amino acids are organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.

Beta hairpin
The beta hairpin (sometimes also called beta-ribbon or beta-beta unit) is a simple protein structural motif involving two beta strands that look like a hairpin.

Beta turn
A β turn is a type of non-regular secondary structure in proteins that causes a change in direction of the polypeptide chain.

Biomolecular structure
Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.

Conformational change
In biochemistry, a conformational change is a change in the shape of a macromolecule, often induced by environmental factors.

Dihedral angle
A dihedral angle is the angle between two intersecting planes.

Enantiomer
In chemistry, an enantiomer, also known as an optical isomer (and archaically termed antipode or optical antipode), is one of two stereoisomers that are mirror images of each other that are non-superposable (not identical), much as one's left and right hands are the same except for being reversed along one axis (the hands cannot be made to appear identical simply by reorientation).

Hydrogen bond
A hydrogen bond is a partially electrostatic attraction between a hydrogen (H) which is bound to a more electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), and another adjacent atom bearing a lone pair of electrons.

Intrinsically disordered proteins
An intrinsically disordered protein (IDP) is a protein that lacks a fixed or ordered three-dimensional structure.

Peptide bond
A peptide bond is a covalent chemical bond linking two consecutive amino acid monomers along a peptide or protein chain.

Proline
Proline (symbol Pro or P) is a proteinogenic amino acid that is used in the biosynthesis of proteins.

Protein folding
Protein folding is the physical process by which a protein chain acquires its native 3-dimensional structure, a conformation that is usually biologically functional, in an expeditious and reproducible manner.

Ramachandran plot
A Ramachandran plot (also known as a Ramachandran diagram or a plot), originally developed in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, is a way to visualize energetically allowed regions for backbone dihedral angles ψ against φ of amino acid residues in protein structure.
