Abstract

Five novel metalloproteinase protein inhibitors (MPIs) with molecular mass between 5.6 and 8.9 kDa and acid/neutral pI were detected in lupin seeds and exhibited strong inhibitory activities against thermolysin and/or gelatinase B. These novel peptides constitute not only the first MPIs described in plants but also the first plant peptides with inhibitory activity against a matrixin.

Keywords: Gelatinase B, lupin quiescent seed, matrixin peptide inhibitor, metalloproteinase protein inhibitor (MPI), thermolysin
