Abstract

The tissue and subcellular distribution of prephenate aminotransferase, an enzyme of the shikimate pathway, was investigated in protoplasts from leaves of Sorghum bicolor. Activity was detected in purified epidermal and mesophyll protoplasts, and in bundle sheath strands. After fractionation of mesophyll and epidermal protoplasts by differential centrifugation, 92% of the total prephenate aminotransferase activity was detected in the plastid fraction.
