Table 2 The intermolecular binding energies of the docked furin-SARS-CoV-2 spike protein complex and A. fumigatus alkaline protease 1-SARS-CoV-2 spike protein. HADDOCK.

From: Aspergillus fumigatus secretes a protease(s) that displays in silico binding affinity towards the SARS-CoV-2 spike protein and mediates SARS-CoV-2 pseudovirion entry into HEK-293T cells
