RESUMO
Phosphoglycerate phosphomutase has been purified to homogeneity from vegetative cells and germinated spores of Bacillus megaterium, and the spore and cell enzymes appear identical. The enzyme is a monomer of molecular weight 61,000. The compound 2,3-diphosphoglyceric acid is not required for activity, but the enzyme has an absolute and specific requirement for Mn2+. The enzyme is inhibited by ethylenediaminetetraacetate and sulfhydryl reagents, has a pH optimum of about 8.0, and has Km values for 3-phosphoglyceric acid and Mn2+ of 5 x 10(-4) and 4 x 10(-5) M, respectively.
