The three electrophoretic variants of phosphoglucomutase in Saccharomyces cerevisiae breeding stocks are produced by two unlinked genes, pgm-1 and pgm-2; pgm-1 contains two known alleles, pgm-1a and pgm-1b, each of which specifies a minor phosphoglucomutase component, and pgm-2 specifies the major phosphoglucomutase component.
Aims/background-In humans there are three phosphoglycerate mutase (PGM, EC 5.4.12.1) isoenzymes (MM, MB and BB) which have similar distribution and developmental pathways to creatine kinase (CK, EC 2.7.3.2) isoenzymes. Total serum PGM activity increases in acute myocardial infarction with the same time course as creatine kinase activity. The present study was undertaken to determine changes in ...
Giardia lamblia, which is an important parasitic cause of diarrhea, uses activated forms of glucose to make glycogen and activated forms of mannose to make glycophosphosphoinositol anchors. A necessary step for glucose activation is isomerization of glucose-6-phosphate to glucose-1-phosphate by a phosphoglucomutase (PGM). Similarly, a phosphomannomutase (PMM) converts mannose-6-phosphate to man...
Pragmatic General Multicast (PGM) is a reliable multicast transport protocol mainly aimed for applications that require ordered, duplicate-free, multicast data delivery from multiple sources to multiple receivers. Each SPM consists of the address of the PGM parent node from which it came. NEs replicate this address with their own when they forward an SPM so that their children will know their p...
We have enriched phosphoglucomutase (PGM; EC 5.4.2.2) approximately 20-fold from Paramecium tetraurelia cells by combined fractional precipitation with (NH4)2SO4, gel filtration and anion-exchange chromatography yielding two PGM peaks. Several parameters affecting PGM enzymic activity, molecular mass and pI were determined. Phosphorylation studies were done with isolated endogenous protein kina...
The functional impact of Pgm amino acid polymorphism on glycogen content in Drosophila melanogaster.
Earlier studies of the common PGM allozymes in Drosophila melanogaster reported no in vitro activity differences. However, our study of nucleotide variation observed that PGM allozymes are a heterogeneous mixture of amino acid polymorphisms. In this study, we analyze 10 PGM protein haplotypes with respect to PGM activity, thermostability, and adult glycogen content. We find a twofold difference...
The Bacillus subtilis genes tpi, pgm, and eno, encoding triose phosphate isomerase, phosphoglycerate mutase (PGM), and enolase, respectively, have been cloned and sequenced. These genes are the last three in a large putative operon coding for glycolytic enzymes; the operon includes pgk (coding for phosphoglycerate kinase) followed by tpi, pgm, and eno. The triose phosphate isomerase and enolase...
BACKGROUND The glycolytic phosphoglycerate mutases exist as non-homologous isofunctional enzymes (NISE) having independent evolutionary origins and no similarity in primary sequence, 3D structure, or catalytic mechanism. Cofactor-dependent PGM (dPGM) requires 2,3-bisphosphoglycerate for activity; cofactor-independent PGM (iPGM) does not. The PGM profile of any given bacterium is unpredictable a...
An unbiased screen for genes that can immortalize mouse embryonic fibroblasts identified the glycolytic enzyme phosphoglycerate mutase (PGM). A 2-fold increase in PGM activity enhances glycolytic flux, allows indefinite proliferation, and renders cells resistant to ras-induced arrest. Glucosephosphate isomerase, another glycolytic enzyme, displays similar activity and, conversely, depletion of ...
Proteo-β-glucan from Maitake (PGM) is a strong immune regulator, and its receptor is called Dectin-1. Cumulative evidence suggests that AMPA receptors are important for the treatment of depression. Here, we report that PGM treatment leads to a significant antidepressant effect in the tail suspension test and forced swim test after sixty minutes of treatment in mice. After five consecutive days ...
