Abstract

Cell wall-bound invertases (EC 3.2.1.26) from both sugar beet seedlings and aged slices of mature roots were purified to homogeneity separately with CM-cellulose chromatography and Bio-Gel P-150 gel filtrations. The enzymes behaved similarly throughout the purification procedures. The purified enzymes are identical as characterized by specific activity, gel electrophoretic mobility, Km for sucrose and raffinose (1.33 and 4.0 millimolar, respectively), mobility on Bio-Gel P-150 (molecular weight 28,000), optimum pH (4.6 to 5.0), optimum temperature, and dependence on NaCl concentration for insolubilization by DNA. The results suggest that the enzymes may be encoded for by the same structural gene.
