In the presented paper are summarized results of the study of the mode of action, dimensions and arrangement of the active centre of the exo-poly-α-D-galacturonosidase, (poly(1,4-α-D-galactosiduronate) digalacturonohydrolase, E.C. 3.2.1.82) produce

Exo-D-galacturonanase (E.C. 3.2.1.67) isolated from carrot was irreversibly adsorbed on poly(ethylene terephthalate) in a 0.1 mol l-1 acetate buffer solution of pH 5.1. Activity of the immobilized enzyme depended on the amount of the enzyme bound to

Two possible modes of action of exo-D-galacturonanase from carrot (E.C. 3.2.1.67) were investigated; this enzyme catalyses the sequential hydrolytic cleavage of pectants and oligogalacturonans by a terminal action from the nonreducing end of the mole

The binding of Cu2+ and Cd2+ ions to potassium oligogalacturonates of polymerization degree DP 1 to 9 was investigated by ion-specific electrodes and by the metallochromic indicator method. The interaction was evaluated on the basis of degree of asso

Exo-D-galacturonanase (E.C. 3.2.1.67) from carrot was immobilized by covalent bonding to a polyacrylamide type support (with free carboxyl groups) activated by water-soluble carbodiimides. The activity of the immobilized enzyme (under optimal reactio

The effect of exo-D-galacturonanase from carrot on O-acetyl derivatives of pectic acid of variousacetylation degree was studied. Substitution of hydroxyl groups at C(2) and C(3) of D-galactopyranuronic acid units influences the initial rate of degrad
