Phosphonoacetaldehyde hydrolase (phosphonatase); similar to Bacillus cereus phosphonatase; Degradation of the ubiquitous natural phosphonate 2-aminoethylphosphonate (AEP) into useable forms of nitrogen, carbon, and phosphorus is a two-step metabolic pathway. The first step, catalyzed by AEP transaminase, involves the transfer of NH3 from AEP to pyruvate, yielding phosphonoacetaldehyde (P-Ald) and alanine. In the second step, phosphonatase catalyzes the hydrolytic P-C bond cleavage of P-Ald to form orthophosphate and acetaldehyde. This family belongs to the haloacid dehalogenase-like (HAD) hydrolases, a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members of this superfamily include 2-L-haloalkanoic acid dehalogenase, azetidine hydrolase, phosphonoacetaldehyde hydrolase, phosphoserine phosphatase, phosphomannomutase, P-type ATPases and many others. HAD hydrolases are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.

It belongs to the beta-phosphoglucomutase-like family whose other members include Lactococcus lactis beta-PGM, a mutase which catalyzes the interconversion of beta-D-glucose 1-phosphate (G1P) and D-glucose 6-phosphate (G6P), Saccharomyces cerevisiae phosphatases GPP1 and GPP2 that dephosphorylate DL-glycerol-3-phosphate, and DOG1 and DOG2 that dephosphorylate 2-deoxyglucose-6-phosphate.
