Biotin labeling of the symbiotically important succinoglycan oligosaccharides of Rhizobium meliloti for identification of putative plant receptors

Carbohydr Res. 2001 Jun 22;333(1):73-8. doi: 10.1016/s0008-6215(01)00125-2.

Abstract

The symbiotically important trimer of the succinoglycan octasaccharide subunit was labeled with a biotin tag through coupling with a 6-biotinamidohexan hydrazide and subsequent reduction with borane. The acetyl and succinyl groups in the molecule were stable to the two-step sequence, while a small percentage of the ketal in the pyruvate groups was reduced to an ether-linked lactic acid moiety attached to either the O-4 or O-6 position of the sugar residue under the reaction conditions.
