Abstract

The precursor of plastocyanin, a thylakoid lumen protein, is imported by castor bean leucoplasts and processed to an intermediate form by a stromal processing peptidase of similar properties and specificity to the corresponding chloroplast enzyme. No further maturation is observed, indicating that the internal protein transport and maturation system present in the chloroplast is absent in leucoplasts.
