partially de-N-acetylated polysaccharide of Escherichia coli K5 strain	the polysaccharide consists of the repeating linear sequence -4GlcAbeta1-4GlcNAcalpha1-. Under controlled conditions for partial digestion, lyase III does not act at the GlcN-GlcA linkage, whereas GlcNAc-GlcA is cleaved. Under forced conditions for exhaustive digestion, the GlcN-GlcA linkage is only partially cleaved	Pedobacter heparinus	(DELTA4,5-unsaturated hexuronic acid)-(N-unsubstituted glucosamine)-(hexuronic acid)-(N-acetylglucosamine)	-	?
