Transglycosylation Capabilities of Wild‐Type α‐l‐Fucosidase iso1 from Paenibacillus thiaminolyticus and Its Engineered Mutants: Preparation of Fucosylated Oligosaccharides [PDF]
Microb BiotechnolSeveral point mutations were introduced into the α‐l‐fucosidase iso1 from Paenibacillus thiaminolyticus (α‐l‐f1Pth‐wt) to enhance its transfucosylation activity. The S237V variant (α‐l‐f1Pth‐S237V) demonstrated superior regioselectivity in the synthesis of 3′‐and 6′‐fucosyllactose and functionalized 3′‐fucosyllactose bearing a Boc‐protected ...
