RA   Berger B.;
RL   Submitted (JUN-2000) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: One of two proteins expressed only when there is a tandem
CC       repeat of the IS21 insertion sequence, it is necessary for the
CC       transposition of plasmids with that tandem repeat.
CC   -!- SIMILARITY: Belongs to the IS21/IS1162 putative ATP-binding protein
CC       family. {ECO:0000305}.
