Feruloyl esterases are enzymes of industrial interest that catalyse the hydrolysis of the ester bond between hydroxycinnamic acids such as ferulic acid and sugars present in the plant cell wall. Although there are several structures of biochemically characterized feruloyl esterases available, the structural determinants of their substrate specificity are not yet fully understood. Here, we present the crystal structure of a feruloyl esterase from Fusarium oxysporum ( Fo FaeC) at 2.3 Å resolution. Similar to the two other tannase‐like feruloyl esterases, Fo FaeC features a large lid domain covering the active site with potential regulatory role and a disulphide bond that brings together the serine and histidine of the catalytic triad. Differences are mainly observed in the metal coordination site and the substrate binding pocket. Enzymes E.C.3.1.1.73 . Databases The sequence of Fo FaeC has been deposited with UniProt with accession code A0A1D3S5H0_FUSOX and the atomic coordinates of the three‐dimensional structure with Protein Data Bank, with PDB code: 6FAT.
