Alpha helix

The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a righthand-spiral conformation (i.e. helix) in which every backbone N−H group donates a hydrogen bond to the backbone C.

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.

Bacterioferritin

Bacterioferritin (Bfr) is an oligomeric protein containing both a binuclear iron centre and haem b. The tertiary and quaternary structure of Bfr is very similar to that of ferritin.

Helix

A helix, plural helixes or helices, is a type of smooth space curve, i.e. a curve in three-dimensional space.

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.

Peptide bond

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