摘要

In lactoferrin-a, the glycans linked to Asn-233 and Asn-545 were of the high-mannose type, whereas those present at Asn-368 and Asn-476 were complex-type ones. These glycans possessed heterogeneous structures. HPLC analyses showed that the structures of glycans linked to Asn-368, Asn-476 and Asn-545 in lactoferrin-a were very similar to those in lactoferrin-b, and that the structure of glycan linked to Asn-233 was different between lactoferrins-a and -b. In addition, the glycan bound to Asn-281 present only in lactoferrin-a was complex-type one, which possessed the heterogeneous structures including Man3GlcNAc2, Man3GlcNAc4 and Man3GlcNAc4Fuc.
