Purification of Rubisco Activase from Leaves or after Expression in Escherichia coli
Time of Update: 2021-01-14
Rubisco activase is a molecular chaperone that modulates the activation state of Rubisco by catalyzing the ATP-dependent removal of tightly-bound inhibitory sugar-phosphates from Rubisco’s catalytic sites. This chapter reports methods developed for the purification of native and recombinant Rubisco activase from leaves and bacterial cells, respectively.
