Restriction digests of the clone give the following sizes (kb): BamHI--2.9; EcoRI--2.9; NcoI--2.9.
Expression vector permitting overproduction and secretion of foreign proteins in an unfused state. The ompA signal sequence directs proteins to the periplasmic space.
pTM-N differs from pTO-N (GenBank accession M34008) only in the bla (ampR) gene. The PstI site in M34008 has been removed in pTM-N.
