protocatechuate 4,5-dioxygenase (LigAB) catalyzes dioxygenation of multiple lignin derived aromatic compounds with decreasing efficiency as the molecule size increases. Residue F103 of the alpha-subunit controls substrate specificity through interaction with the C5-funtionality of bound substrates. In silico docking of substrates to the enzyme mutants, overview
