==THREE-DIMENSIONAL STRUCTURE OF RAT ACID PHOSPHATASE IN COMPLEX WITH L(+) TARTRATE==
-
The crystal structure of recombinant rat prostatic acid phosphatase in complex with the inhibitor L(+)-tartrate was determined to 3-A resolution with protein crystallographic methods. The inhibitor binds at the carboxyl end of the parallel strands of the alpha/beta domain. One of the carboxyl groups of the tartrate molecule interacts with the conserved residues Arg-11, His-12, and Arg-15, which form part of the phosphate binding site. Furthermore, the C2 and C3 hydroxyl groups interact with His-257 and Arg-79. The second carboxyl group is close to Arg-79 but makes no direct hydrogen bonds to the protein. A sequence comparison between tartrate-sensitive and -resistant acid phosphatases suggests that these enzymes have different three-dimensional structures.

== Function ==
 +
[https://www.uniprot.org/uniprot/PPAP_RAT PPAP_RAT] A non-specific tyrosine phosphatase that dephosphorylates a diverse number of substrates under acidic conditions (pH 4-6) including alkyl, aryl, and acyl orthophosphate monoesters and phosphorylated proteins. Has lipid phosphatase activity and inactivates lysophosphatidic acid in seminal plasma (By similarity). Isoform 2: the cellular form also has ecto-5'-nucleotidase activity in dorsal root ganglion (DRG) neurons. Generates adenosine from AMP which acts as a pain suppressor.
