A Medicago truncatula homoglutathione synthetase is derived from glutathione synthetase by gene duplication.

Glutathione (GSH) and homo-GSH (hGSH) are the major low-molecular weight thiols synthesized in Medicago truncatula. Two M. truncatula cDNAs (gshs1 and gshs2) corresponding to a putative GSH synthetase (GSHS) and a putative hGSH synthetase (hGSHS) were characterized. Heterologous expression of gshs1 and gshs2 cDNAs in an Escherichia coli strain deficient in GSHS activity showed that GSHS1 and GS...

Site Directed Mutagenesis of Schizosaccharomyces pombe Glutathione Synthetase Produces an Enzyme with Homoglutathione Synthetase Activity

Three different His-tagged, mutant forms of the fission yeast glutathione synthetase (GSH2) were derived by site-directed mutagenesis. The mutant and wild-type enzymes were expressed in E. coli DH5α and affinity purified in a two-step procedure. Analysis of enzyme activity showed that it was possible to shift the substrate specificity of GSH2 from Gly (k(m) 0,19; wild-type) to β-Ala or Ser. One...

Post-translational regulation of cytosolic glutamine synthetase of Medicago truncatula.

It was reported recently that the plastid-located glutamine synthetase (GS2) from Medicago truncatula is regulated by phosphorylation catalysed by a calcium-dependent protein kinase and 14-3-3 interaction. Here it is shown that the two cytosolic GS isoenzymes, GS1a and GS1b, are also regulated by phosphorylation but, in contrast to GS2, GS1 phosphorylation is catalysed by calcium-independent ki...

Differential expression within the glutamine synthetase gene family of the model legume Medicago truncatula.

The glutamine synthetase (GS) gene family of Medicago truncatula Gaertn. contains three genes related to cytosolic GS (MtGSa, MtGSb, and MtGSc), although one of these (MtGSc) appears not to be expressed. Sequence analysis suggests that the genes are more highly conserved interspecifically rather than intraspecifically: MtGSa and MtGSb are more similar to their homologs in Medicago sativa and Pi...

Glutathione synthetase from Plasmodium falciparum.

GSH is the major low-molecular-mass thiol in most organisms. The tripeptide maintains a reduced intracellular environment and protects cellular components from damaging oxidation. GSH is synthesized by the action of two ATP-dependent enzymic steps, in which gamma-glutamylcysteine synthetase (gamma-GCS) catalyses the ligation of glutamate and cysteine and subsequently glutathione synthetase (GS)...
