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 ...

Alpha (α)-isomer

Biology; Biochemistry

In sugar chemistry, the anomer that places the hemiacetal (or hemiketal) hydroxy group on the side of the pyranose (or furanose) ring opposite the non-ring carbon atom (i.e. C-6 of glucose) that is ...

BZIP protein

Biology; Biochemistry

A type of Y-shaped homodimeric DNA-binding protein in which the stem is composed of two intertwined α-helices held together as a leucine zipper; the arms of the Y are the basic regions that reach ...

HLH protein

Biology; Biochemistry

One of a group of proteins defined by their characteristic topography (the helix-loop-helix). These proteins form DNA-binding heterodimers composed of two proteins, one from a ubiquitous and one from ...
