cellobiohydrolases are exo-active glycosyl hydrolases that processively convert cellulose to soluble sugars, typically cellobiose. Occuring opposite effects on binding and activity by the enzyme can be reconciled if the rate-limiting step is after the catalysis (i.e. in the dissociation process), analysis of the rate-limiting step for cellobiohydrolases, overview
