    FlAlyA is an endolytic enzyme with a preference for polymannuronate. The crystal structure and mutagenesis studies elucidated that the structural variations at outer uronate-binding subsites +2, +3 and -2 control the enzymatic properties of PL-7 family enzymes. Lys158 mutations changed the pH dependency and enhanced the production of mono- and disaccharides.
