RuBisCO is believed to be the most abundant enzyme on earth, and catalyses a critical step in carbon fixation. Assisted by different assembly factors, including Raf1, RuBisCO assembles into the holoenzyme comprising eight large subunits (RbcL) and eight small subunits (RbcS). Here, the researchers resolve high-resolution protein structures of the cyanobacterial RuBisCO octameric complex that reflect different steps of its assembly.
