Table 1. Comparative steady-state affinity analysis of WT-LmFPPS and mutants for FPP and GPP using SPR.
Steady-state affinity ‘KD’ and the maximum response “Rmax’ were estimated from non-linear regression by fitting the equilibrium binding data to steady-state affinity equation. ND- not determined.
