Description

The AAA+ ATPase Rubisco activase (Rca) regulates the activity of Rubisco, the photosynthetic enzyme responsible for catalyzing biological carbon fixation. However, the detailed mechanism by which Rca self-association controls Rubisco

The AAA+ ATPase Rubisco activase (Rca) regulates the activity of Rubisco, the photosynthetic enzyme responsible for catalyzing biological carbon fixation. However, the detailed mechanism by which Rca self-association controls Rubisco reactivation activity remains poorly understood. In this work, we are using fluorescence correlation spectroscopy (FCS) to better characterize the thermodynamics of the assembly process of cotton Rca. We present FCS data for Rca in the presence of Mg*ATPgS and Mg*ADP and for the D173N Walker B motif mutant in the presence of Mg*ATP.
