Utilization of Natural Fucosylated Oligosaccharides by Three Novel α-L-Fucosidases from a Probiotic Lactobacillus casei Strain
Rodríguez-Díaz, Jesús | Monedero, Vicente | Yebra, María J.
Three putative α-L-fucosidases encoded in the Lactobacillus casei BL23 genome were cloned and purified. The proteins displayed different abilities to hydrolyze natural fucosyloligosaccharides like 2'-fucosyllactose, H antigen disaccharide, H antigen type II trisaccharide, and 3'-, 4'-, and 6'-fucosyl-GlcNAc. This indicated a possible role in the utilization of oligosaccharides present in human milk and intestinal mucosa.
