Acceptor-substrate recognition by N-acetylglucosaminyltransferase-V: Critical role of the 4 ″-hydroxyl group in β-D-GlcpNAc-(1→ 2)-α-D-Manp (1→ 6)-β-D-Glcp-OR

The enzyme N-acetylglucosaminyltransferase-V (GlcNAcT-V) transfers GlcNAc from UDP-
GlcNAc to the OH-6′ group of oligosaccharides terminating in the sequence β-d-GlcpNAc-
(1→ 2)-α-d-Manp (1→ 6)-β-d-Glcp (or Manp)-OR (5, R(CH 2) 7 CH 3) to yield the
sequence β-d-GlcpNAc-(1→ 2)-[β-d-GlcpNAc-(1→ 6)]-α-d-Manp-(1→ 6)-β-d-Glcp (or Manp)-
OR. Biosynthetically, if β-(1→ 4)-galactosyltransferase acts first on 5, the product β-d-Galp-
(1→ 4)-β-d-GlcpNAc-(1→ 2)-α-d-Manp-(1→ 6)-β-d-Glcp (or Manp)-OR (7) is no longer a …
