A Proteinase from Germinating Barley : I. Purification and Some Physical Properties of a 30 kD Cysteine Endoproteinase from Green Malt.

abstract：:alpha-Amylases are important enzymes for starch degradation in plants. However, it has been a long-running debate as to whether alpha-amylases are localized in plastids where starch is stored. To study the subcellular localization of alpha-amylases in plant cells, a rice (Oryza sativa) alpha-amylase, alphaAmy3, with o...
