<p>The rate of dissociation of PLP from the <i>e</i>PL kinase•PLP complex was followed by observing the change in optical activity of the bound PLP at 37°C. Panel A: Spectra of the complex (60 µM) at time zero (curve a) and after 120 min in the presence of 10 µM PLP phosphatase (curve b). Panel B: measured decrease in optical activity after addition of PLP phosphatase at 415 nm with time and as an exponential process with rate constant of 0.012 min<sup>−1</sup>.</p
