Contributors in Biochemistry

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 ...

open reading frame (ORF)

Biology; Biochemistry

One of three possible reading frames in which an mRNA is potentially translated into protein. In analysis of a DNA sequence, an ORF is characterized by the sequence of nucleotides that when ...
