Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Matrix metalloproteinases (MMPs) or matrixins may play a role in the degradation and remodeling of the extracellular matrix (ECM) during development or in response to stresses (By similarity). Required for plant growth, morphogenesis, and development with particular relevance for flowering and senescence (PubMed:11726650). Active on McaPLGLDpaAR-NH2 (QF24) and myelin basic protein (MBP) and, to some extent, on beta-casein (PubMed:24156403).By similarity2 Publications
Cofactori
Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
Activity regulationi
Repressed by acetohydroxamic acid (AHA).1 Publication
pH dependencei
Optimum pH is 7-8.1 Publication
Temperature dependencei
Optimum temperature is 45 degrees Celsius.1 Publication

Expressioni
Tissue specificityi
Mostly expressed in roots, and, to a lower extent, in flowers, leaves and stems.2 Publications
Developmental stagei
Accumulates during aging. Expressed in leaves and roots of young seedlings and in leaves, roots, and inflorescences of mature flowering plants. In leaves, present in the phloem, in developing xylem elements, epidermal cells, and neighboring mesophyll cell layers. In flowers, localized in pistils, ovules, and receptacles.1 Publication
Inductioni
Induced in seedling rosette leaves by methyl jasmonate (MeJA) and cadmium (Cd). Induced in seedling roots by salt stress (NaCl). Inhibited in leaves and inflorescences of adult plants by exposure to cadmium.1 Publication

Domaini
The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.By similarity
