Protein Variants | Comment | Organism |
---|---|---|
additional information | engineered low-glycosylated variant of glucoamylase 1 with a short linker, low-glycosylated GA1 (dgGA). Low-glycosylated linker variant of GA1; GA1:L0 and dgGA:L0 | Aspergillus niger |
Inhibitors | Comment | Organism | Structure |
---|---|---|---|
additional information | binding of a short heterobidentate inhibitor simultaneously directed toward the catalytic and starch binding domains causes dimerization of glucoamylase and not, an intramolecular conformational rearrangement mediated by linker flexibility | Aspergillus niger |
