Lacto-N-biosidase

Lacto-N-biosidase (EC 3.2.1.140) is an enzyme with systematic name oligosaccharide lacto-N-biosylhydrolase.

[1][2] This enzyme catalyses the following chemical reaction The enzyme from Streptomyces specifically hydrolyses the terminal lacto-N-biosyl residue (beta-D-Gal-(1->3)-D-GlcNAc) from the non-reducing end of oligosaccharides with the structure beta-D-Gal-(1->3)-beta-D-GlcNAc-(1->3)-beta-D-Gal-(1->R).
