Contributors in Biochemistry

Biochemistry

A structure common to a large group of proteins, all of which are enzymes, defined by their similar structural motif. A ring of eight parallel β-strands makes up the core; the end of each β-strand is ...

Genomic library

Biology; Biochemistry

A collection of transformed cells, each of which contains DNA fragments; the entire population represents the total genome of an organism, e.g. a rat library containing DNA fragments which together ...

Molecular matchmaker

Biology; Biochemistry

A protein that effects complex-formation between another protein and DNA by catalysis of an energy-dependent conformational change in at least one of the pair; it thereby increases affinity and ...

Peripheral nervous system (PNS)

Biology; Biochemistry

A division of the nervous system of higher animals that consists of the neurons that extend from the spinal cord to skeletal muscles, glands, etc. and the neurons that return from these structures to ...

Axial

Biology; Biochemistry

Descriptive of the orientation of a substituent on a six-membered ring that is perpendicular to the plane of the ring; the opposite of equatorial, which is the orientation substantially within the ...

Footprinting

Biology; Biochemistry

A group of techniques for identification of protein-binding sites on DNA. In dimethylsulfate (DMS) footprinting, for example, an end-labelled DNA fragment is partially methylated at guanidine ...

Paradox of Levinthal

Biology; Biochemistry

The discrepancy between the enormous number of conformations a polypeptide may assume and the rapidity with which it normally achieves its native conformation. It excludes the possibility that each ...
