ABSTRACT IS 1, the smallest active transposable element in bacteria, encodes a
transposase that promotes inter-and intramolecular transposition. Host-encoded factors, eg …

The transposase (InsAB′) of the insertion element IS 1 can create breaks in DNA that lead
to induction of the SOS response. We have used the SOS response to InsAB′ to screen for …

The transposase of IS 911, a member of the IS 3 family of bacterial insertion sequences, is
composed of a catalytic domain located at its C‐terminal end and a DNA binding domain …

The genome of the transposable element IS2 contains five open reading frames that are
capable of encoding proteins greater than 50 amino acids; however, only one IS2 protein of …

The inverted repeats (IRs) of the insertion element IS903 are composed of two functional
regions. An inner region, consisting of basepairs 6–18, is the transposase binding site. The …

IS629 is 1,310 bp in length with a pair of 25-bp imperfect inverted repeats at its termini. Two
partially overlapping open reading frames, orfA and orfB, are present in IS629, and two …

The transposase of the bacterial insertion sequence IS1 is normally expressed by inefficient
translational frameshifting between an upstream reading frame which itself specifies a …

The movement of the bacterial insertion sequence IS 50 and of composite elements
containing direct terminal repeats of IS 50 involves the two ends of IS 50, designated O …

IS30 is the founding member of a large family of widely spread bacterial insertion sequences
with closely related transposases. The N‐terminal end of the IS30 transposase had been …

The insertion element IS1 has two open reading frames (ORFs), insA and insB, and
produces a transframe protein InsAB, known as IS1 transposase, by translational …
