The aromatic ammonia–lyase from Loktanella atrilutea (LaAAL) displays a high activity towards 3,4-dimethoxy trans–cinnamic acid, with a surprisingly diminished activity towards natural AAL substrates. Under the optimal reaction conditions LaAAL exhibited versatility for the transformation of various cinnamic acids. While LaAAL might be classified as a tyrosine ammonia-lyase (TAL, E.C. 4.3.1.23), its
