... chitosan chains from their ends (as opposed to an endo-action), and thus is an exoenzyme. If ChiB were to be a processive enzyme, one would expect chain movements by an even number of sugar units, as ... structure of ChiB sug- gests that the enzyme exerts exo-activity and degrades chitin chains from their nonreducing ends [16,20]. It is generally accepted that enzymes that degrade carbohyd...
