Summary: Acid Phosphatase
Acid Phosphatase Provide feedback
This family contains phosphatase enzymes and other proteins of the HAD superfamily. It includes MDP-1 which is a eukaryotic magnesium-dependent acid phosphatase [1-2].

InterPro entry IPR010036
This entry represents two closely related clades of sequences from eukaryotes and archaea. The mouse enzyme has been characterised as a phosphatase and has been positively identified as a member of the haloacid dehalogenase (HAD) superfamily by site-directed mutagenesis of the active site residues [PUBMED:11601995, PUBMED:10889041].
The mapping between Pfam and Gene Ontology is provided by InterPro. If you use this data please cite InterPro.

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Acid_PPase domain has been found. There are 6 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
