Escherichia coli K-12 substr. MG1655 Polypeptide: IS186/IS421 transposase



Gene: insL-1 Accession Numbers: G6083 (EcoCyc), b0016, ECK0016

Synonyms: yi81-1

Regulation Summary Diagram: ?

Summary:
IS186 is an insertion sequence element that appears three times in a typical E. coli genome.

IS186 is an insertion sequence element with an apparent preference for GC-rich sequences [Kothary85, Chong85]. As a consequence, it can insert at the tail end of cDNA clones [Chong85]. At the DNA level, the various IS186 genes have terminal inverted repeats and produce variable-length DNA duplications at the insertion site (10, 12 or 13 bp) [Kothary85, Chong85].

Locations: cytosol

Map Position: [15,445 -> 16,557] (0.33 centisomes)
Length: 1113 bp / 370 aa

Molecular Weight of Polypeptide: 40.909 kD (from nucleotide sequence)
