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.
In biochemistry, two biopolymers are antiparallel if they run parallel to each other but with opposite alignments.
The β-sheet (also β-pleated sheet) is a common motif of regular secondary structure in proteins.
Bond cleavage, or scission, is the splitting of chemical bonds.
Deoxyribonucleic acid (DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.
Enzymes are macromolecular biological catalysts.
A Holliday junction is a branched nucleic acid structure that contains four double-stranded arms joined together.
The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms.
Molecular biology is a branch of biology which concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
A protein domain is a conserved part of a given protein sequence and (tertiary) structure that can evolve, function, and exist independently of the rest of the protein chain.
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.
Ribonuclease (commonly abbreviated RNase) is a type of nuclease that catalyzes the degradation of RNA into smaller components.
Schizosaccharomyces pombe, also called "fission yeast", is a species of yeast used in traditional brewing and as a model organism in molecular and cell biology.
A sequence in biology is the one-dimensional ordering of monomers, covalently linked within a biopolymer; it is also referred to as the primary structure of the biological macromolecule.
In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a supersecondary structure, which also appears in a variety of other molecules.
