✦ Synopsis

The structure of an extracellular polysaccharide (S-130) elaborated by Alcaligenes ATCC 31555, has been investigated. It is concluded that the polysaccharide is composed of pentasaccharide units having the following structure: ~3)-P_D-Glcp-(1~4)-P-D-GlcpA-(1~4)-PD-Glcp-(1~4)-ar-L-Rhap-(l~ ; 1 a-t-Rhap or cw-L-Manp

Of these units, approximately two-thirds contain terminal cu-L-rhamnopyranosyl groups; the remainder contain a-L-mannopyranosyl groups. Approximately 50% of the units contain an 0acetyl group.
