The soluble acidic invertase from barley shoots and the soluble basic invertase from shoots and roots were purified by ion-exchange chromatography and gel filtration. The purified proteins were homogenous by the gel electrophoretic criterion. The amino acid ratios of the acidic invertase from shoots and the basic enzyme from roots reflect their isoelectric behavior. The acidic enzyme contains about 49% glucan and 0.7% glucosamine.
