The heterologous BuGH16 agarase is enzymatically functional in engineered B. theta strains. (a) Schematic model of BuGH16 endo-agarase activity agarose to generate neoagarooligosaccharides (NAOS). NAOS is a repeating disaccharide of l-3,6-anhydro-galactose (L-3,6) and d-galactose, with L-3,6 at the non-reducing end. (b) pINT integrated hexa-histidine tagged BuGH16 (black arrow) detected by Western blot from induced SusRDX strains. (c) Thin-layer chromatography of culture supernatant from induced engineered strains incubated with agarose shows the presence of NAOS (black bar) generated from agarose by active BuGH16.
