additional information
-
SDS-PAGE of the purified protein shows that EBM II is comprised of six polypeptides with molecular masses of 65000, 46000, 42000, 31000, 28000 and 27000 Da. Analysis of the fragments disclose EBM II consists of endo-beta-mannosidase and an associated protein that has slight homology to the fucosidase domain of the bifidus AfcA protein
