The quality validation of wild type and mutant SARS-CoV-2 helicase models.

Server	SARS-CoV-2 Helicase WT by MODELLER 9.15	SARS-CoV-2 Helicase WT	SARS-CoV-2 Helicase Mutant
ERRAT	56.661	81.2613	81.522
RAMPAGE	Number of residues in favoured region: 514 (90.2%) Number of residues in allowed region: 67 (8.2%) Number of residues in outlier region: 13 (1.7%)	Number of residues in favoured region: 514 (86.5%) Number of residues in allowed region: 67 (11.3%) Number of residues in outlier region: 13 (2.2%)	Number of residues in favoured region: 514 (86.5%) Number of residues in allowed region: 67 (11.3%) Number of residues in outlier region: 13 (2.2%)
PROSA z-score	−8.75 (the model in X-ray region)	−8.72 (the model in X-ray region)	−8.55 (the model in X-ray region)
PROQa	Predicted LGscore: 4.906	Predicted LGscore: 5.196	Predicted LGscore: 5.140
VERIFY3Db	85.36% of the residues have averaged 3D-1D score ≥0.2	88.09% of the residues have averaged 3D-1D score ≥0.2	87.92% of the residues have averaged 3D-1D score ≥0.2
Chimera Superimpose with template (RMSD)	0.283 Å	0.128 Å	0.126 Å

^aQuality ranges of PROQ scores: LGscore>1.5 fairly good model; LGscore>2.5 very good model; LGscore>4 extremely good model. MaxSub>0.1 fairly good model; MaxSub>0.5 very good model; MaxSub>0.8 extremely good model.

^bThe amino acids must be scored as at least 80% for evaluation as a good model.
