Abstract
A trypsin/chymotrypsin inhibitor (CpTI) was purified from mature cowpea seeds. A full length cDNA clone encoding the trypsin/chymotrypsin inhibitor protein was isolated from a cDNA library that was constructed using poly(A+) RNA from developing seeds. Tobacco protoplasts were transformed with a construct composed of CaMV 35S promoter, NPTII gene, CpTI gene, and NOS terminator, using polyethylene glycol (PEG)-mediated direct gene transfer. The CpTI gene has been integrated into the plant genome, and the expressed CpTI protein from transgenic plants was catalytically active.
