Glutamine synthetase (GS) is encoded by three distinct gene families (GSI, GSII, and GSIII) that are broadly distributed among the three domains of life. Previous studies established that GSII and GSIII isoenzymes were expressed in diatoms; however, less is known about the distribution and evolution of the gene families in other chromalveolate lineages. Thus, GSII cDNA sequences were isolated from three cryptophytes (Guillardia theta D. R. A. Hill et Wetherbee, Cryptomonas phaseolus Skuja, and… 
Molecular Evolution of Nitrogen Assimilatory Enzymes in Marine Prasinophytes
TLDR
The results show that genes encoding the nitrogen-assimilating enzymes in Micromonas and Ostreococcus have been differentially lost and as well as recruited from different evolutionary lineages, suggesting that the regulation of nitrogen assimilation in prasinophytes will differ from other green algae.
Glutamine Synthetase Drugability beyond Its Active Site: Exploring Oligomerization Interfaces and Pockets
TLDR
The PPI of three GSs—human (hsGS), maize (zmGS) and Mycobacterium tuberculosis (mtGS)—is mapped and a novel drugable pocket was detected on the mtGS PPI, which seems particularly promising for the development of selective anti-tuberculosis drugs given its location on a PPI region that is highly populated with hot-spots.

GLUTAMINE SYNTHETASE IN MARINE ALGAE: NEW SURPRISES FROM AN OLD ENZYME
TLDR
The presence of genes encoding GSIII in diatoms and haptophytes indicates that this enzyme family is more broadly distributed in eukaryotes than previously suspected.
Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution
TLDR
Phylogenetic evidence suggests GSIIB in Chloroplastida evolved by HGT, possibly after the divergence of the primary endosymbiotic lineages, and the isoenzymes may have evolved via different evolutionary processes.
Evolutionary relationships of bacterial and archaeal glutamine synthetase genes
TLDR
It is suspected that the similarity of GSI-α genes from Euryarchaeota and several bacterial species does not reflect a common phylogeny but rather lateral transmission between archaea and bacteria.
Tryptophan Biosynthesis in Stramenopiles: Eukaryotic Winners in the Diatom Complex Chloroplast
TLDR
The entire pathway is of eukaryotic origin and cytosolic localization in oomycetes; however, one of the enzymes, anthranilate phosphoribosyl transferase, was likely transferred to the oomyCete nucleus from the red algal nucleus during secondary endosymbiosis, suggesting possible retention of the complex plastid in the ancestor of stramenopiles and later loss of this organelle in oomers.
A nuclear gene of eubacterial origin in Euglena gracilis reflects cryptic endosymbioses during protist evolution.
TLDR
It is suggested that the early-branching protists Giardia lamblia and Entamoeba histolytica and portions of the trypanosome lineage have acquired GAPDH genes from eubacterial donors which did not ultimately give rise to contemporary membrane-bound organelles.
CHARACTERIZATION OF A cDNA ENCODING GLUTAMINE SYNTHETASE FROM THE MARINE DIATOM SKELETONEMA COSTATUM (BACILLARIOPHYCEAE)
TLDR
Results from Southern blot analysis of genomic DNA suggested that the cDNA isolated in this study was either a member of a small, highly conserved gene family or that there was allelic variation within the region examined, supporting the hypothesis that GS isoenzymes in diatoms, green algae, and vascular plants arose through independent evolutionary events.
Molecular analysis of a novel glutamine synthetase of the anaerobe Bacteroides fragilis.
TLDR
The nucleotide sequence of a 2777 bp DNA segment containing the Bacteroides fragilis glnA gene was determined and a glutamine synthetase subunit of 729 amino acid residues with a calculated Mr of 82,827 was determined.
Isoforms of Glutamine Synthetase in the Marine Coccolithophorid Emiliania huxleyi (Prymnesiophyceae)
Abstract Two isoenzymes of glutamine synthetase (EC 6.3.1.2), GS 1 and GS 2 , have been purified from cells of Emiliania huxleyi using Cibacron blue dye ligand chromatography and gel filtration,
A glyceraldehyde-3-phosphate dehydrogenase with eubacterial features in the amitochondriate eukaryote, Trichomonas vaginalis
TLDR
GAPDHs of other amitochondriate protists, belonging to early branches of the eukaryotic lineage (Giardia lamblia and Entamoeba histolytica)—Smith M.W. and Doolittle R.F., unpublished data in GenBank), showed typical eubacterial signatures and clustered with other eUKaryotic sequences, indicating that T. vaginalis GAPDH occupies an anomalous position.
Principles of Protein and Lipid Targeting in Secondary Symbiogenesis: Euglenoid, Dinoflagellate, and Sporozoan Plastid Origins and the Eukaryote Family Tree 1 , 2
TLDR
It is argued that dinoflagellate and sporozoan plastids are directly related and that the common ancestor of dinof lagellates and Sporozoa was photosynthetic, and a novel theory for the function of periplastid vesicles in membrane biogenesis of chlorarachneans and chromists is proposed.
