Description (2-aminoethyl)phosphonate--pyruvate aminotransferase
Notes 2-Aminoethylphosphonate (ciliatine) is the precursor of an array of phosphonated compounds (e.g., phosphonopolysaccharides), which are employed by some organisms for specialized functions such as chemical warfare, cell-cell communication, and host recognition.

Enzymes in this family may be involved both in the synthesis and the degradation of ciliatine; their sequences are distantly related to those in the dhap aminotransferase family and to those of classic alanine-glyoxylate aminotransferases (family

Some biosynthetic enzymes (such as the enzyme from Treponema denticola) are part of bifunctional proteins containing also a N-terminal nucleotidyl transferase domain, which has been removed from the sequences included in the family.
