pectinase Biochem.|ˈpɛktɪneɪz, -s|
[a. F. pectinase (E. Bourquelot 1899, in Jrnl. de Pharm. et de Chimie IX. 567): see pectin and -ase.]
An enzyme found in plants and in certain bacteria and fungi which hydrolyses pectin to its constituent monosaccharides.
1899Jrnl. Chem. Soc. LXXVI. i. 652 In all probability it is a new ferment and the name pectinase is suggested for it. 1929R. A. Gortner Outl. Biochem. xxvii. 593 Pectinase hydrolyzes pectin (and possibly pectic acid) to its simple components, sugars and galacturonic acid. 1953F. T. Brooks Plant Dis. (ed. 2) x. 156 Brown..has indicated that the enzyme (pectinase) or enzyme complex of B. cinerea which softens the cell walls probably also kills the host protoplasm. 1972Materials & Technol. V. 703 They [sc. the pectic enzymes] can be broadly classified,..into two sub-groups. These are the polygalacturonases, which cleave glycosidic linkages between adjoining galacturonic acid units, and the pectic methyl esterases... The two groups were formerly known, respectively, as pectinases and pectases. |
