Figure 1From: A membrane-bound matrix-metalloproteinase from Nicotiana tabacum cv. BY-2 is induced by bacterial pathogensNucleotide and amino acid sequences of NtMMP1. The signal peptide sequence (aa 1–20) is shown in bold. The seven potential N-glycosylation sites are shown in bold italics. The so-called cysteine switch motif is underlined, the zinc binding region within the catalytic domain is double underlined and the predicted hydrophobic transmembrane helix is underlined in bold.Back to article page
