Sialidases are glycoside hydrolases that cleave sialosides. Here the authors define the 3-D structure, alone and in complex with products and inhibitors, of the CAZy family GH156 sialidase, EnvSia156, showing it displays a catalytical (β/α) 8-barrel domain distinct from other sialidases and allowing description of its inverting catalytic mechanism.
