The haloacid dehydrogenase superfamily (HAD superfamily) is a superfamily of enzymes that include phosphatases, phosphonatases, P-type ATPases, beta-phosphoglucomutases, phosphomannomutases, and dehalogenases, and are involved in a variety of cellular processes ranging from amino acid biosynthesis to detoxification.[1]

Examples
editA HAD domain is found in several distinct proteins including:
- Phospholipid-translocating ATPase EC 3.6.3.1, a putative lipid-flipping enzyme involved in cold tolerance in Arabidopsis [2]
- 3-deoxy-D-manno-octulosonate (KDO) 8-phosphate phosphatase (EC 3.1.3.45), which catalyses the final step in the biosynthesis of KDO - a component of lipopolysaccharide in Gram-negative bacteria[3]
- Mannosyl-3-phosphoglycerate phosphatase (EC 3.1.3.70), which hydrolyses mannosyl-3-phosphoglycerate to form the osmolyte mannosylglycerate[4]
- Phosphoglycolate phosphatase (EC 3.1.3.18), which catalyses the dephosphorylation of 2-phosphoglycolate[5]
- 5´-Nucleotidase (EC 3.1.3.5) which either catalyzes the hydrolysis of IMP. or IMP and GMP
- Hypothetical proteins
Human genes encoding proteins that contain this domain include:
