CC   -!- FUNCTION: Involved in phosphonate degradation. {ECO:0000255|HAMAP-
CC       Rule:MF_01376}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2-aminoethyl)phosphonate + pyruvate = L-alanine +
CC         phosphonoacetaldehyde; Xref=Rhea:RHEA:17021, ChEBI:CHEBI:15361,
CC         ChEBI:CHEBI:57418, ChEBI:CHEBI:57972, ChEBI:CHEBI:58383; EC=2.6.1.37;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01376};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01376};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01376}.
CC   -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC       aminotransferase family. PhnW subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_01376}.
CC   -!- CAUTION: The second enzyme involved in phosphonate degradation (PhnX,
CC       EC 3.11.1.1) is not found in this organism. The function of this enzyme
CC       is therefore uncertain. {ECO:0000305}.
