UVvis spectrum of LcpRr and LcpK30 before and after the addition of 1 mM imidazole (as isolated/after reduction) in the area of the Q-band. No significant change was observable for LcpK30 whereas for LcpRr a substantial increase at 560 nm was determined upon addition of imidazole. Assays were repeated two times with two separate protein batches. A typical experiment is shown
