When the temperature is too hot, a
rubisco helper protein,
rubisco activase, shuts down, photosynthesis stops, and the plant stops growing.
Arid-Land Agricultural Research Center, has teamed with Rebekka Wachter, associate professor of chemistry and biochemistry at Arizona State University, and Nathan Henderson, her postdoctoral research associate, to crystallize
rubisco activase.

The carboxysome, a polyhedral protein microcompartment found in all cyanobacteria and in many chemoautotrophs, is filled with ribulose-1,5-bisphosphate carboxylase/oxygenase (
RubisCO), the enzyme that catalyzes the fixation of C[O.sub.2] onto ribulose-1,5-bisphosphate and produces two molecules of 3-phosphoglycerate.
Large subunit of
Rubisco (53kDa) was absent in V- -seedlings (Fig.
