The invertase inhibitory protein isolated from Cyphomandra betacea Sendt and Solanum tuberosum inhibited the invertase activity from different species, genera and even plant family. Furthermore, proteinaceous inhibitors are not invertase specific; fu

The invertase from Equisetum giganteum L., a lower vascular sporophytic plant, was purified to chromatographic and electrophoretic homogeneity. The enzyme appears to be a pentamer, M r 91,000, formed by identical subunits ( M r 18,000). An isoelectri

Three fractions with invertase activity (beta-D-fructofuranoside fructohydrolase, EC 3.2.1.26) were isolated from mature Solanum tuberosum tubers: acid soluble invertase, invertase I and invertase II. The first two invertases were purified until elec

An acid-soluble invertase from Nicotiana glauca has been studied for the first time. The plant was selected because it is known that the genus Nicotiana has vacuolar alkaloids; the same localization of the acid-soluble invertases in higher plants. Th
