 Enzyme reactions 
   Enzyme class 1: E.C.  - Protein-serine/threonine phosphatase.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: [a protein]-serine/threonine phosphate + H2O = [a protein]- serine/threonine + phosphate
[a protein]-serine/threonine phosphate
+ H(2)O
= [a protein]- serine/threonine
+ phosphate
   Enzyme class 2: E.C.  - Protein-tyrosine-phosphatase.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate
Protein tyrosine phosphate
+ H(2)O
= protein tyrosine
+ phosphate
Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.

Figure 1.
Figure 1. (a) C trace of the DUSP5-C structure (black) superimposed with that of VHR (red; pdb code, 1VHR). The regions of DUSP5-C that cannot be aligned are shown in green. The secondary structural elements of DUSP5-C are labeled black whereas the secondary structural elements unique to VHR are labeled red. GA indicates the position of the general acid loop. (b) The active site of DUSP5-C. The active site of DUSP5-C (ivory) is superimposed with that of MKP3 (grey). C263S-R269, D232, and bound sulfate ion are shown for DUSP5-C, whereas C293-R299 and D262 are shown for MKP3. The hydrogen bonding interactions for DUSP5-C are indicated with dotted lines. The residues of DUSP5-C are shown in black whereas those for MKP are labeled red. Some side-chains were omitted from the drawing for clarity. (c) C trace of the DUSP5-C structure (black) is superimposed with that of the MKP-3 structure (red; pdb code, 1MKP). The regions of DUSP5-C that cannot be aligned are shown in green. The secondary structural elements for DUSP5-C are shown in black, whereas the secondary structural elements unique to MKP-3 are shown in red. (d) Ribbon diagram of a DUSP5-C dimer. Protomers A and B are shown in magenta and grey, respectively. Catalytically active residues, C263(A) and C263(B) and bound sulfate ions are represented with ball-and-stick models. (e) Stereodiagram of the 2Fo-Fc electron density map around the active site superposed on the refined model. The map is contoured at 1.2 level. The residues are represented as a ball-and-stick model.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
