| Abstract: | Some propertise of two types of polygalacturonases (PG1 and PG2) in pectinasewere compared. Tlie optimum conditions of their activities, the stability of the enzymes, theeffects of some metal ions on the activity of the enzymes, kinetic parameters, molecularweiglit. composition of aniino acids are niarkedly different from each other- But the activityof eacli niolecular enzynie of PG1 and PG2 is similar and both of them are acidic proteins. |
