Abstract

By in vivo [3H]mevalonate labelling of spinach combined with biochemical analysis, evidence is provided for the existence of protein prenylation in chloroplasts. Approximately 20 prenylated polypeptides were resolved by SDS-PAGE followed by autoradiography. Thermolysin treatment of intact chloroplasts revealed that about 40% of the prenylated polypeptides were associated with the cytoplasmic surface of the outer envelope membrane. The remaining portion was present in thylakoids and/or the inner envelope membrane. The majority of the prenylated polypeptides were associated with larger membrane protein complexes. A farnesyl protein transferase activity was found to be associated with the thylakoid membrane.
