Notes:
Tissues of barley caryopsis and seedling were examined for the protease, BAPAase, and an inhibitor. The enzyme was present in extracts of alevn-one but was absent from aleurone incubation media and extracts of: embryo with scutellum; seedling with scutellum and rootlets, and endosperm that was free of aleurone tissue. The enzyme was present in non-incubated aleurone and did not increase significantly during incubation under conditions where alpha-amylase increased in the medium and tissue. Addition of gibberellie acid produced no detectable increase in BAPAase.Extracts of endosperm had weak BAPAase-inhibitory activity; embryo or seedling extracts produced strong inhibition. The inhibitor present in these extracts was dialyzable.
