Figure 3From: Regulatory and structural properties differentiating the chromosomal and the bacteriophage-associated Escherichia coli O157:H7 Cu, Zn Superoxide DismutasesSignal peptide sequences from bacterial Cu, ZnSODs. Signal peptidase I and II cleavage sites were identified through the Lipo P program. The alignment of the signal peptides of bacterial Cu, ZnSOD is based on the Leu-X-Y-Cys motif.Back to article page
