Ligand	Binding Affinity of Ligand-Protein Complex (kcal/mol)
	MurA	GBAP	Gelatinase	Serine Protease
Catechin	−8.5	−5.2	−7.8	−7.0
Fosfomycin	−4.6	−3.1	−4.6	−3.8
Ambuic acid	−7.8	−4.5	−6.6	−6.5
Quercetin	−8.5	−5.2	−8.3	−6.9
Taxifolin	−9.1	−5.1	−7.9	−6.5

Quercetin, fosfomycin, ambuic acid, and taxifolin were used as positive controls.
