^a From Refs. 22, 23, and 27–29.

^b From Refs. 27–32.

^c From Refs. 17, 19–22, 31, 34, and 35.

^d Different GH29 fucosidases show specificities toward various natural linkages. pNP-Fuc activity is reported to be high for most GH29 fucosidases except plant and bacterial GH29 α1,3/4-fucosidases or FgFCO1.

^e From Refs. 15 and 26.
