Intact leucoplasts from the endosperm of developing castor oil seed were isolated by Percoll density gradient centrifugation. The precursor to the small subunit of ribulose 1,5-bisphosphate carboxylase from pea was synthesized in vitro from hybrid-selected mRNA. Leucoplasts imported this precursor by an ATP-requiring mechanism similar to that described in chloroplasts (AR Grossman et al. 1980 Nature 285: 625-628). The small subunit precursor was processed to a molecular weight that was identical with that of the mature pea small subunit. These results show that leucoplasts, though specialized for fatty acid biosynthesis and not photosynthesis, have a mechanism of protein import similar to that of chloroplasts.
