title: Purification, characterization and immunological properties of 2,3-bisphosphoglycerate-independent phosphoglycerate mutase from maize (Zea mays) seeds.
abstract: 2,3-Bisphosphoglycerate-independent phosphoglycerate mutase (EC 5.4.2.1) was purified and characterized from maize. SDS electrophoresis showed only one band with a molecular mass of 64 kDa, similar to that determined for the native enzyme by gel-filtration chromatography. The kinetic constants were similar to those reported for wheat germ phosphoglycerate mutase. Rabbit antiserum against maize phosphoglycerate mutase possesses a high degree of specificity. It also reacts with the wheat germ enzyme but fails to react with other cofactor-independent or cofactor-dependent phosphoglycerate mutases. Cell-free synthesis experiments indicate that phosphoglycerate mutase from maize is not post-translationally modified.
