A membrane-bound matrix metalloproteinase from Nicotiana tabacum cv. BY-2 is induced by bacterial pathogens

Abstract

Our biochemical analysis of NtMMP1 together with bioinformatic data on the primary sequence indicate that NtMMP1 is a constitutively-active protease. Given its induction in response to bacterial pathogens and its localization in the plasma membrane, we propose a role in pathogen defense at the cell periphery.
