Background Methionine adenosyltransferase (MAT) is a ubiquitous essential enzyme that, in eukaryotes, occurs in two relatively divergent paralogues: MAT and MATX. MATX has a punctate distribution across the tree of eukaryotes and, except for a few cases, is mutually exclusive with MAT. This phylogenetic pattern could have arisen by either differential loss of old paralogues or the spread of one of these paralogues by horizontal gene transfer. Our aim was to map the distribution of MAT/MATX genes within the Euglenida in order to more comprehensively characterize the evolutionary history of MATX.

Abstract S-Adenosylmethionine synthetase has been purified to apparent homogeneity from human chronic lymphocytic leukemia cells. Equilibrium sedimentation studies and denaturing polyacrylamide gel electrophoresis indicate that the native enzyme has a molecular weight of 185,000 and a subunit composition of either alpha alpha' beta 2, alpha 2 beta 2, or alpha' 2 beta 2, where alpha, alpha', and beta are polypeptide chains of molecular weight 53,000, 51,000, and 38,000. The alpha and alpha' subun...

Translation elongation factor 1α (EF-1α, or EF-Tu in bacteria) is a highly conserved core component of the translation machinery that is shared by all cellular life. It is part of a large superfamily of GTPases that are involved in translation initiation, elongation, and termination, as well as several other cellular functions. Eukaryotic EF-1α (eEF-1α) is well studied and widely sampled and has been used extensively for phylogenetic analyses. It is generally thought that such highly conserved a...

Next generation sequencing (NGS) technologies provide a high-throughput means to generate large amount of sequence data. However, quality control (QC) of sequence data generated from these technologies is extremely important for meaningful downstream analysis. Further, highly efficient and fast processing tools are required to handle the large volume of datasets. Here, we have developed an application, NGS QC Toolkit, for quality check and filtering of high-quality data. This toolkit is a standa...

Abstract Polymerase chain reaction conditions were established for the in vitro amplification of eukaryotic small subunit ribosomal (16S-like) rRNA genes. Coding regions from algae, fungi, and protozoa were amplified from nanogram quantities of genomic DNA or recombinant plasmids containing rDNA genes. Oligodeoxynucleotides that are complementary to conserved regions at the 5' and 3' termini of eukaryotic 16S-like rRNAs were used to prime DNA synthesis in repetitive cycles of denaturation, reann...

Elongation factor 1α (EF-1α) and elongation factor-like (EFL) proteins are considered to carry out equivalent functions in translation in eukaryotic cells. Elongation factor 1α and EFL genes are patchily distributed in the global eukaryotic tree, suggesting that the evolution of these elongation factors cannot be reconciled without multiple lateral gene transfer and/or ancestral co-occurrence followed by differential loss of either of the two factors. Our current understanding of the EF-1α/EFL e...

Abstract The structure of S-adenosylmethionine synthetase (MAT, ATP:L-methionine S-adenosyltransferase, EC from Escherichia coli has been determined at 3.0 A resolution by multiple isomorphous replacement using a uranium derivative and the selenomethionine form of the enzyme (SeMAT). The SeMAT data (9 selenomethionine residues out of 383 amino acid residues) have been found to have a sufficient phasing power to determine the structure of the 42,000 molecular weight protein by combining...

Abstract Methionine adenosyltransferase from Euglena gracilis (MATX) is a recently discovered member of the MAT family of proteins that synthesize S-adenosylmethionine. Heterologous overexpression of MATX in Escherichia coli rendered the protein mostly in inclusion bodies under all conditions tested. Therefore, a refolding and purification procedure from these aggregates was developed to characterize the enzyme. Maximal recovery was obtained using inclusion bodies devoid of extraneous proteins b...

Methionine adenosyltransferases (MATs) are the family of enzymes that synthesize the main biological methyl donor, S-adenosylmethionine. The high sequence conservation among catalytic subunits from bacteria and eukarya preserves key residues that control activity and oligomerization, which is reflected in the protein structure. However, structural differences among complexes with substrates and products have led to proposals of several reaction mechanisms. In parallel, folding studies begin to e...

Background EFL (or elongation factor-like) is a member of the translation superfamily of GTPase proteins. It is restricted to eukaryotes, where it is found in a punctate distribution that is almost mutually exclusive with elongation factor-1 alpha (EF-1α). EF-1α is a core translation factor previously thought to be essential in eukaryotes, so its relationship to EFL has prompted the suggestion that EFL has spread by horizontal or lateral gene transfer (HGT or LGT) and replaced EF-1α multiple tim...

Petalomonads are particularly important for understanding the early evolution of euglenids, but are arguably the least studied major group within this taxon. We have established a culture of the biflagellate petalomonad Notosolenus urceolatus, and conducted electron microscopy observations and molecular phylogenetic analysis. Notosolenus urceolatus has eight pellicular strips bordered by grooves and underlain by close-set microtubules. There are ventral and dorsal Golgi bodies. Mitochondria appa...

Euglenophyceae (phototrophic euglenids) are an important lineage within the Euglenida, Euglenozoa. Most of the approximately 3,000 described species are free-living, phototrophic, unicellular flagellates with one to several plastids of secondary origin, three bounding membranes and chlorophylls a and b; but, the lineage also includes colorless species that lost their photosynthesizing capability. They show a typical cell membrane consisting of parallel proteinaceous strips and microtubules locat...
