GlucaM shared no significant similarity with these glucoamylases (<10% identity), indicating that GlucaM may be a novel glucoamylase.
The activity of GlucaM was independent of Ca2+.
GlucaM is also highly resistant to high salt concentrations and various detergents.
rGlucaM could act on different substrates and maltooligosaccharides, making it a good catalyst for production of glucose
