additional information | - |
during the thermal inactivation progress, combined with the loss of the helical structure and a majority of the tertiary structure, tryptophan residues are partially exposed and further lead to glucoamylases aggregating. The thermal stability of isoforms GAM-1 and GAM-2 is largely improved in the presence of sorbitol and trehalose by maintaining the native state of glucoamylases and preventing their thermal aggregation | Aspergillus niger |
