A protein that is functional at one temperature but loses function at another (usually higher) temperature.
Industry:Biotechnology
A protein that prevents RNA polymerase from terminating transcription at specific transcription termination sequences.
Industry:Biotechnology
A protein which binds to a specific DNA sequence (the operator) upstream from the transcription initiation site of a gene or operon and prevents RNA polymerase from commencing mRNA synthesis. Examples of repressors are the C<sub>1</sub> protein of bacteriophage and the <i>lac</i>1 protein of the <i>lac</i> operon.
Industry:Biotechnology
A protein whose amino acid sequence is encoded by a cloned gene.
Industry:Biotechnology
A protein-replication complex that catalyses the initiation of synthesis of Okazaki fragments during discontinuous replication of DNA. It involves DNA primase and DNA helicase activities.
Industry:Biotechnology
A proteolytic enzyme that hydrolyzes peptide bonds on the carboxyl side of the amino acids arginine and lysine.
Industry:Biotechnology
A protocol for labelling DNA <i>in vitro</i>. A sample of random oligonucleotides (6 or 14 nucleotides long) containing all possible combinations of nucleotide sequences is hybridized to a DNA probe. Then, in the presence of a DNA polymerase and the four deoxyribonucleotides - one of which is labelled - the 3´ hydroxy ends of the hybridized oligonucleotides provide initiation sites for DNA synthesis that uses the separated strands of the probe DNA as a template. This reaction produces labelled copies of portions of the probe DNA.
Industry:Biotechnology
A purification technique in which an antibody is bound to a matrix and is subsequently used to bind and separate a protein from a complex mixture.
