Figure 6
FF to LU transition state like conformation.
(A) Comparison of the FFlike active site of EcAhpC1-186-YFSKHN (brown) with the typical FF conformation in the reduced StAhpC (light blue), where the C-terminal tail is folded across the active site (blue), which is disordered in reduced EcAhpC1-186-YFSKHN. (B) The oxidized- (green) and reduced (salmon) active sites observed in the EcAhpC1-186-YFSKHN structures are compared with the reduced StAhpC (light blue) FF active site. The intermediate FFlike (brown) and LUlike (salmon) conformations, represent the transition state from the FF to the LU state. (C) Another view to close look at the comparison of FF, LU, FFlike and LUlike active sites.
