Blood-group endo-β-galactosidase 98A from Streptococcus pneumoniae, Recombinant

Cat No.

NATE-1411

Description

Blood-group-substance endo-1,4-beta-galactosidase (EC 3.2.1.102, endo-beta-galactosidase, blood-group-substance 1,4-beta-D-galactanohydrolase) is an enzyme with systematic name blood-group-substance 4-beta-D-galactanohydrolase.[1][2][3] This enzyme catalyses the following chemical reaction: Endohydrolysis of (1->4)-beta-D-galactosidic linkages in blood group A and B substances. Hydrolyses the 1,4-beta-D-galactosyl linkages adjacent to a 1,3-alpha-D-galactosyl or N-acetylgalactosaminyl residues and a 1,2-alpha-D-fucosyl residue.
