Molecular biology

The observation, first based on inspection of structures and later on experimentation, that many biological substances (e.g. sterols, tocopherols, rubber) appear to have been assembled from multiple ...

Edman degradation

Biology; Biochemistry

A chemical technique to degrade and cleave amino acid residues sequentially from a protein beginning at the N-terminus, and to identify the residues as they are removed. Reaction of the N-terminal ...

alpha/beta (α/β)-hydrolase fold

Biology; Biochemistry

A structure common to a group of proteins, including esterases, carboxypeptidases and dehalogenases, that have a catalytic triad of nucleophile, histidine and carboxylate positioned on a scaffolding ...

cis-acting

Biology; Biochemistry

Descriptive of the controlling effect of a regulatory gene on a structural gene that is adjacent to it; later broadened to distinguish intramolecular (cis) from intermolecular (trans) actions.

phase transition

Biology; Biochemistry

A melting-like phenomenon that occurs when lipid bilayers are warmed, usually below the naturally occurring temperature of a plasma membrane; due to thermal disruption of the regular stacking of ...

axoneme

Biology; Biochemistry

The fundamental structural unit of eukaryotic flagella and cilia; it is composed of nine microtubular doublets (in cross-section a microtubule with another fused to it) surrounding two microtubule ...

singlet state

Biology; Biochemistry

An excited electronic state in which an electron is raised to a higher energy level without reversal of its spin state, and thus is easily able to fall back to its ground state, often with a ...
