Model confidence (pLDDT)

The mean pLDDT of this model is 96.1 (very high overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

pLDDT band	Meaning	Share of residues
Above 90	Very high: backbone and side chains are usually accurate	96%
70 to 90	Confident: backbone generally right	1%
50 to 70	Low: treat with caution	0%
Below 50	Very low: often disordered regions	3%

What pLDDT means and how to read it

Function

Glucoside hydrolase that cleaves the alpha-1,3-glucosidic linkage in nigerose. Has very low activity towards maltooligosaccharides, soluble starch, nigerotriose, kojibiose and trehalose
