Rice α-fucosidase (α-fucosidase Os, 58 kDa) that is active for α1-4 fucosyl linkage in Lewis a unit of plant N-glycans was purified to homogeneity. α-fucosidase Os showed activity against α1-3 fucosyl linkage in Lacto-N-fucopentaose III but not α1-3 fucosyl linkage in the core of plant N-glycans. The N-terminal sequence of α-fucosidase Os was identified as A-A-PT- P-P-P-L-, and this sequence was found in the amino acid sequence of the putative rice α-fucosidase 1 (Os04g0560400).
