Sialosyl-fucosyl poly-LacNAc without sialosyl-Lexepitope in myeloid cell line HL60 was shown to be the ligand for E-selectin-dependent adhesion, particularly under dynamic flow conditions, in our previous study (Handa K, Stroud MR, Hakomori S,Biochemistry36, 12412–12420, 1997). HL60 cells express only fucosyltransferase (FT) IV and VII. X3NeuAcVII3FucnLc10, a representative component showing E-selectin-dependent binding under dynamic flow conditions, is not α1 → 3 fucosylated at the penultimate GlcNAc catalyzed by FT-VII, but is α1 → 3 fucosylated at the internal GlcNAc catalyzed by FT-IV. VI3NeuAcnLc6is converted to VI3NeuAcIII3FucnLc6by FT-IV, but is also converted to VI3NeuAcV3FucnLc6by FT-VII. Thus, penultimate fucosylation catalyzed by FT-VII is not restricted for nLc6backbone, but is highly restricted for nLc10backbone. The cooperative effect of FT-IV and FT-VII for synthesis of poly-LacNAc having sialosyl-Lexwith internal fucosylation may be blocked or highly restricted in poly-LacNAc having more than two LacNAc units, because preferential α1 → 3 fucosylation by FT-IV takes place at internal GlcNAc, inhibiting penultimate fucosylation by FT-VII.
