transposase --> transposon
(Science: molecular biology) small, mobile dNA sequences that can replicate and insert copies at random sites within chromosomes.
Transposase
An enzyme (or enzyme complex) required for the transposition of a particular transposable element.
Transposase
Class of proteins responsible for transposition. One function is to prepare insertion by cutting at the integration site.

Transposase binds to:
both ends of the transposon, which consist of inverted repeats; that is, identical sequences reading in opposite directions.
a sequence of DNA that makes up the target site.
Class II transposons usually move by cut and paste, rather than copy and paste, using the transposase enzyme. Different types of transposase work in different ways.
It is a sequence of DNA that encodes an enzyme called transposase, which enables the IS to move. The transposase gene is flanked on either side by fifteen to twenty-five base pairs, arranged as "inverted repeats.
The simplest kind of a transposon, consisting of inserted repeats of DNA flanking a gene for transposase, the enzyme that catalyzes transposition.

Autonomous transposons encode a transposase and are capable of transposing on their own. Transposition of non-autonomous elements requires trans-activation from the autonomous element.
Insertion sequence A simple DNA transposon, composed of a kilobase sequence that specifies a transposase and is bounded on either end by inverted terminal repeats; an insertion sequence can insert itself into any site on a bacterial chromosome.
transposon - mobile segment of DNA capable of "hopping" into or out of chromosomal DNA; a complete transposon encodes an enzyme called a transposase that can mediate the excision and insertion of the transposon DNA. (See also retrotransposon) ...
Group of transposable elements that were detected by Saedler, Starling and Shapiro. They constist of 800 to 2000 base pairs and carry inverted repeats at their ends. The central part consists of reading frames and codes for transposases responsible ...
Only a single copy of a transposase gene, belonging to the Tn3 family and located on plasmid pSOL1, could be identified. Two gene clusters of four genes each show similarity to bacteriophage-like elements. There are 11 ribosomal operons.
