Molecular biology

An analog of a polypeptide, a poly-glycine in which the backbone nitrogen atoms are substituted with groups the same as or different from those of natural amino acids. Although these polymers do not ...

alpha (α)-configuration

Biology; Biochemistry

In steroid chemistry, the orientation of substituents below the plane of the ring system, i.e. on the side opposite the angular methyl groups at C-10 and C-13, which have the β-configuration. ...

thioredoxin

Biology; Biochemistry

This is a small redox-active protein with an exposed dithiol motif (-CXXC-) that cycles between a disulphide and a dithiol. The dithiol reduced form is an important cofactor in a number of biological ...

sequential feedback

Biology; Biochemistry

A control mechanism for a branched metabolic pathway. The end product of each branch inhibits the first enzymic step of its own branch, which results in an accumulation of the last metabolite of the ...

Eisenberg plot

Biology; Biochemistry

A graphical representation of the hydrophobic moment ;μ M ; against the mean hydrophobicity ;H; of an α-helix. α-Helices of globular proteins generally have low ;μ M ; and low ;H; values; membrane ...

meta-

Biology; Biochemistry

A prefix derived from the Greek for with or after, which indicates association or intermediacy. In benzene derivatives, meta- signifies the relation of substances on nuclear carbon atoms two removed ...

nested deletion sequencing

Biology; Biochemistry

A method for extension of the length of a target DNA that can be sequenced using a single primer. Removal by an appropriate nuclease of varying polydeoxynucleotide lengths from the region near the ...
