Characterization of the exo-acting mannuronan (M) lyase Nonul2377. (A) Representative degradation kinetic revealing the poly-M substrate specificity. Incubation on standard alginate substrates was conducted, at least, with two independent production of enzymes. (B) The exolytic mode of action of the enzymes was visualized using size-exclusion chromatography. Δ: 4-deoxy-L-erythro-5-hexoseulose uronic acid.
