Description L-serine ammonia-lyase.
Notes The validated serine ammonia-lyases come from fungi and animals; accordingly, the family is constituted by fungal and metazoan proteins only (although some very similar bacterial sequences can be found in databases).

Note that, in some bacteria, the deamination of L-Ser is carried out by L-threonine ammonia lyase (EC and the corresponding enzymes have been included in that family.

Note also that some bacteria possess PLP-independent L-serine ammonia-lyases.
