Preparation and Purification of Glucanase and Chitinase from Bean Leaves
Open accessAbstract
Glucanase (endo-beta-1, 3-glucan 3-glucanohydrolase, EC 3.2.1.6, laminarinase, callase) and chitinase (poly-beta-1, 4-[2-acetamido-2-deoxy] -d-glucoside glycanohydrolase, EC 3.2.1.14) were extracted from ethylene-treated bean (Phaseolus vulgaris L. cv. Red Kidney) leaves and purified on hydroxyapatite and carboxymethyl Sephadex columns. The glucanase prepared was homogeneous as judged by analytical centrifugation data, electrophoresis, and antibody-antigen reactions. On the basis of gel filtration, antibody-antigen reactions, and amino acid analysis, the molecular weight was estimated to be between 11,500 and 12,500. However, ultracentrifugation gave a higher estimate of 34,000. The glucanase had an isoelectric point near pH 11 and was specific for beta-1, 3-linkages. The chitinase was only partially purified as judged by electrophoretic behavior.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
