Phosphatase Classification: Superfamily Cys-based III
The superfamily share the common CX5R motif with another two cysteine-based superfamilies, Superfamily Cys-based I and Superfamily Cys-based II. Although the member families have very divergent sequences, they have similar fold to each other and all of them has CX5R motif.
The superfamily consists of two member families present in human low molecular weight PTP (LWMPTP) and SSU72. Although human LMWPTP and SSU72 exhibit low sequence identity (15%), the overall folds are very close to each other. The rmsd (root mean square deviation) of 1.7 Å when superimposing SSU72 (PDB ID: 3OMW) with LMWPTP (PDB ID: 1XWW) [1].
The subfamily has an additional member only present in prokaryotes, arsenate reductase (ArsC). It has low sequence identity with LMWPTP and SSU72, 19% between Golden Staph ArsC (PDB ID: 1LJL) and mouse LMWPTP (PDB ID: 2P4U), 16% between Golden Staph ArsC and fruit fly SSU72 (PDB ID: 3FMV). But, ArsC has very similar structure with LMWPTP as shown in SCOP database.
