Origin: Formed within English, by derivation. Etymons: poly- comb. form, galacturonic adj., -ase suffix.

Etymology: < poly- comb. form + galacturon- (in galacturonic adj.) + -ase suffix. Compare German Polygalakturonase (1955 or earlier; also Polygalacturonase).

Biochemistry.

= pectinase n.

1936 I. Kertesz in Ergebnisse der Enzymforschung 5 244 The snaillichenase and the commercial emulsin (Merck) showed only low ‘pectolase’ (polygalacturonase) activity.

1973 Biochimica et Biophysica Acta–Enzymology 309 363 At levels of enzymes forming reducing groups at equal rates, polygalacturonase II was much more effective than polygalacturonase I in reducing the viscosity of pectic acid.

2000 New Scientist 4 Mar. 31/3 The purée is made from tomatoes genetically engineered..to contain a short section of the gene for polygalacturonase, an enzyme which digests the cell walls in ripening fruit.
