Determination of the Relative Equilibrium Association Constant (K_r) for the Three Chimeric Proteins with Purified Insoluble Chitin, as Described By Gilkes et al.²⁸

	BlaPChBDI	BlaPChBDII	BlaPChBDIII
Kr (L g−1)	5.4 ± 0.5	7.4 ± 0.7	10.1 ± 0.3

Each binding constant has been determined in two independent experiments (each performed in triplicates) using very low protein concentrations (see Materials and Methods section). The presented values correspond to the averages ± SD of these two independent experiments.
