In the previous version of the model, the model was simulated based on the iterative concept only; however, in real conditions multiple enzyme molecules act simultaneously and block the hydrolysis sites for each other (Igarashi et al. 2011).
The low Km value is consistent with the low KD for nonspecific DNA binding and supports the contention, described above, that the concentration dependence of the single-turnover reaction of MCsp arises from multiple enzyme molecules performing an intramolecular transfer step.

The processivity of glycanases has been studied by means of biochemical experiments so far17; however, this is problematic because of the great difficulty in distinguishing between multiple exo-type reactions catalysed by plural enzyme molecules and a processive reaction catalysed by a single molecule.

The latter (approximately 70 ~ 80% of starch) is a much larger molecule with frequent α-(1 6) branches formed by multiple enzymes, for example, starch synthases (SSs) and starch branching enzymes (SBEs) (Tetlow et al. 2004; Hannah and James 2008).
