additional information | amino acids S191/D240 of PGI are unique in binding the pectin backbone and are possibly crucial for its specificity. D240 and R96 of PGI work as crampons to favour the sliding of the substrate | Aspergillus niger |
additional information | amino acids S234/S91 of PGII are unique in binding the pectin backbone and are possibly crucial for its specificity | Aspergillus niger |
additional information | amino acids S245/V89 of PG are unique in binding the pectin backbone and are possibly crucial for its specificity | Fusarium fujikuroi |
