Fig. 5From: Elucidation of degrading pattern and substrate recognition of a novel bifunctional alginate lyase from Flammeovirga sp. NJ-04 and its use for preparation alginate oligosaccharidesESI-MS analysis of products with a tetrasaccharide, b pentasaccharide, c hexasaccharide, d heptasaccharide, and e octasaccharide as substrate. f Putative action pattern of FsAlgB towards different substrates. Arrows indicate possible cleavage sites of FsAlgB toward saturated oligosaccharide chains. Solid arrow represented prior cleavage, while dotted arrow represented secondary cleavage. ΔDPn(n = 1–4) represents unsaturated oligosaccharides with DP of 1–4Back to article page
