From: Biosynthesis of the nosiheptide indole side ring centers on a cryptic carrier protein NosJ
SPR measurements of NosJ binding to its reaction partners. NosI a and NosK b showed rapid binding and dissociation kinetics, whereas NosN c showed a relatively slow kinetics. K D represents equilibrium dissociation constant, whereas k a and k d represent the rate constants of association and dissociation, respectively. Sensorgrams are shown in solid lines with different colors corresponding to different concentrations, and the fittings in c are shown in dashed black lines
