Rubisco is a rare example of an enzyme whose genetic information is found in two different cellular compartments.

Question

Quizplus · Accepted Answer

Rubisco, or ribulose-1,5-bisphosphate carboxylase/oxygenase, is an enzyme involved in the first major step of carbon fixation in the photosynthetic process. Its genetic information is indeed found in two different cellular compartments: the chloroplast and the nucleus. The large subunit of Rubisco is encoded by the chloroplast genome, while the small subunit is encoded by nuclear genes. This distribution necessitates a coordinated expression and assembly of the subunits for the functional enzyme to form.
