title: The Low CO2-Inducible 36-Kilodalton Protein Is Localized to the Chloroplast Envelope of Chlamydomonas reinhardtii.
abstract: The localization of the 36-kD polypeptide of Chlamydomonas reinhardtii induced by photoautotrophic growth on low CO2 concentrations (0.03% in air [v/v], low CO2-grown cells) has been investigated. This polypeptide was specifically localized to the chloroplast envelope membranes isolated from low CO2-grown cells and was not present in the chloroplast envelopes isolated from high (5% CO2 in air [v/v]) CO2-grown cells. The 36-kD protein does not show carbonic anhydrase activity and was not present on the plasma membranes isolated from low CO2-grown cells. This protein may, in part, account for the different inorganic carbon uptake characteristics observed in chloroplasts isolated from high and low CO2-grown cells of C. reinhardtii.
