Phosphatase Classification: Superfamily Cys-based III
This superfamily has a unique fold, but shares the common CX5R catalytic motif with another two cysteine-based superfamilies, superfamily Cys-based I and superfamily Cys-based II.
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 similar. 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.
