Rubisco Assembly chaperone C-terminal domain
This is the C-terminal domain, also known as the beta domain, of Rubsico Assembly Chaperone protein (Raf1). Raf1 is necessary for rubisco to catalyze the rate-limiting step of carbon fixation through carboxylating the five-carbon sugar substrate ribulose-1,5-bisphosphate. The beta domains primary function is dimerization, which is critical for Raf1 to achieve the necessary avidity for complex formation with RbcL (the large complex sub-unbit of Rubsico) assembly intermediates. The beta domain is also involved, to a small extent, in binding to RbcL with use of the lustiness near the beta domain's conserved top surface.
