  ABSTRACT  
 
Bacillus stearothermophilus phosphoglycerate mutase (PGM), which interconverts 2- and 3-phosphoglyceric acid (PGA), does not require 2,3-diphosphoglyceric acid for activity. However, this enzyme does have an absolute and specific requirement for Mn(2+) ions for catalysis. Here we report the crystal structure of this enzyme complexed with 3PGA and manganese ions to 1.9 A resolution; this is the first crystal structure of a diphosphoglycerate-independent PGM to be determined. This information, plus the location of the two bound Mn(2+) ions and the 3PGA have allowed formulation of a possible catalytic mechanism for this PGM. In this mechanism Mn(2+) ions facilitate the transfer of the substrate's phosphate group to Ser62 to form a phosphoserine intermediate. In the subsequent phosphotransferase part of the reaction, the phosphate group is transferred from Ser62 to the O2 or O3 positions of the reoriented glycerate to yield the PGA product. Site-directed mutagenesis studies were used to confirm our mechanism and the involvement of specific enzyme residues in Mn(2+) binding and catalysis.

Figure 3.
Figure 3 (A) The interaction of active site residues with the 3PGA substrate and Mn^2+ ions. A total of 14 residues constitute the active site of iPGM. These include residues interacting with Mn^2+ ions and residues interacting with 3PGA. (B) Coordination sphere of Mn^2+ ions. The coordination sphere of both Mn^2+ ions is distorted square pyramidal. The atoms occupying the apex positions are NE2 of His462 for Mn1 and OG of Ser62 for Mn2.
Figure 5.
Figure 5 The mechanism of phosphate group transfer from 3PGA to 2PGA by B.stearothermophilus iPGM. The major intermediates in the proposed catalytic mechanism are described in the text and are depicted as follows: (A) binding of 3PGA in the active site (based on the X–ray coordinates); (B) formation of a phosphoserine intermediate; (C) repositioning of the glycerate; (D) formation of 2PGA (based on the coordinates of the 2PGA–enzyme complex model); and (E) dissociation of the 2PGA–enzyme complex.

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 codes are shown on the right.
