Abstract

Three -glucan-hydrolysing enzymes from Ig4a have been isolated. Two of them are dextranases which hydrolyse (1→6) but not (1→3) linked --glucans; one (EC 3.2.1.11,1,6---glucan 6-glucanohydrolase) is localized in the periplasm, and the other, which is an exo-enzyme (EC 3.2.1.70,1,6---glucan glucohydrolase), in the cytoplasm. The third is a mutanase (EC 3.2.1.59, 1,3-(1,3;1,4)---glucan 3-glucanohydrolase) that hydrolyses (1→3) but not (1→6) linked --glucans, and is present only in the cytoplasm.
