title: Phylogeny and ontogeny of the phosphoglycerate mutases--IV. Distribution of glycerate-2,3-P2 dependent and independent phosphoglycerate mutases in algae, fungi, plants and animals.
abstract: 1. The distribution of the glycerate-2,3-P2 dependent and independent phosphoglycerate mutases (PGM) has been studied in more than eighty species. 2. PGM activity in the extracts has been measured in the presence and in the absence of glycerate-2,3-P2, at pH 7.5 and at pH 8.5. 3. All samples with glycerate-2,3-P2 dependent PGM possess higher activity at pH 7.5 than at pH 8.5. In contrast, samples with glycerate-2,3-P2 independent PGM possess lower activity at pH 7.5 than at pH 8.5. 4. In algae and fungi both glycerate-2,3-P2 dependent and independent PGM have been found. 5. In plants only glycerate-2,3-P2 independent PGM has been detected. 6. In animals both types of PGM are present. Independent PGM activity is present in sponges, coelenterates, myriapods, arachnids and echinoderms. Glycerate-2,3-P2 dependent PGM is present in platyhelminths, mollusks, annelids, crustaceans, insects and vertebrates.
