The growing interest in proteins exported by bacteria led to the devel
opment of cloning vectors designed for targeting recombinant proteins
to extracytoplasmic compartments. The pIN-III-ompA vector family fulfi
ls such a function. Here we report the construction and sequencing of
new pIN-III-ompA derivatives with alternate polylinker sites, increasi
ng the cloning flexibility of these vectors. (C) 1998 Elsevier Science
