The Lineweaver-Burk plot of the peptide VY-9 when inhibiting (a) mono-phenolase activity and (b) di-phenolase activity. Reactions were carried out at varying inhibitor concentrations: No inhibitor (filled black circle), 0.25 mM (filled red circles), 0.5 mM (filled green circle), and 1.0 mM of VY-9 (filled blue circle). Lineweaver-Burk secondary plots revealed the determination of the inhibitor constant (Ki) in inhibiting (c) mono-phenolase activity and (d) di-phenolase activity by the peptide VY-9.
