Genes for tryptophan biosynthesis in the archaebacterium Haloferax volcanii.

ABSTRACT: Recent technical advances permit direct genetic approaches for isolating genes and mapping auxotrophic mutations in the halophilic archaebacterium (Archaea) Haloferax volcanii. Twenty-nine mutations in tryptophan biosynthesis mapped to two separate chromosomal locations. DNA sequencing of one gene cluster shows a unique gene order (trpCBA) and unusual potential secondary structures in the 5'-flanking region.

Genes for tryptophan biosynthesis in the halophilic archaebacterium Haloferax volcanii: the trpDFEG cluster.

Project description:Tryptophan auxotrophs of the archaebacterium Haloferax volcanii define a cluster of overlapping genes homologous to eubacterial-eukaryotic trpD, -F, -E, and -G, linked in that order and each preceded by a possible ribosome binding site. Residues involved in feedback inhibition of eubacterial anthranilate synthetases are conserved.

Tryptophan biosynthesis genes trpEGC in the thermoacidophilic archaebacterium Sulfolobus solfataricus.

Project description:A DNA fragment containing the trpEGC gene cluster was isolated from the thermoacidophilic archaebacterium Sulfolobus solfataricus. The products of trpE, trpG, and trpC from S. solfataricus were compared to the homologous products from a eukaryote, a eubacterium, and two archaebacteria, namely, a methanogen and an extreme halophile. They appeared to be equally related to the proteins from Escherichia coli and Saccharomyces cerevisiae, the percentages of conserved amino acids being roughly the same as those measured when comparing the eubacterial and eukaryotic sequences directly. These percentages did not rise significantly when a comparison with the proteins from Haloferax volcanii was drawn, while a slightly closer relationship with the proteins from Methanococcus thermoautotrophicum was found.

Haloferax volcanii N-glycosylation: delineating the pathway of dTDP-rhamnose biosynthesis.

Project description:In the halophilic archaea Haloferax volcanii, the surface (S)-layer glycoprotein can be modified by two distinct N-linked glycans. The tetrasaccharide attached to S-layer glycoprotein Asn-498 comprises a sulfated hexose, two hexoses and a rhamnose. While Agl11-14 have been implicated in the appearance of the terminal rhamnose subunit, the precise roles of these proteins have yet to be defined. Accordingly, a series of in vitro assays conducted with purified Agl11-Agl14 showed these proteins to catalyze the stepwise conversion of glucose-1-phosphate to dTDP-rhamnose, the final sugar of the tetrasaccharide glycan. Specifically, Agl11 is a glucose-1-phosphate thymidylyltransferase, Agl12 is a dTDP-glucose-4,6-dehydratase and Agl13 is a dTDP-4-dehydro-6-deoxy-glucose-3,5-epimerase, while Agl14 is a dTDP-4-dehydrorhamnose reductase. Archaea thus synthesize nucleotide-activated rhamnose by a pathway similar to that employed by Bacteria and distinct from that used by Eukarya and viruses. Moreover, a bioinformatics screen identified homologues of agl11-14 clustered in other archaeal genomes, often as part of an extended gene cluster also containing aglB, encoding the archaeal oligosaccharyltransferase. This points to rhamnose as being a component of N-linked glycans in Archaea other than Hfx. volcanii.

Extracellular DNA metabolism in Haloferax volcanii.

Project description:Extracellular DNA is found in all environments and is a dynamic component of the microbial ecosystem. Microbial cells produce and interact with extracellular DNA through many endogenous mechanisms. Extracellular DNA is processed and internalized for use as genetic information and as a major source of macronutrients, and plays several key roles within prokaryotic biofilms. Hypersaline sites contain some of the highest extracellular DNA concentrations measured in nature-a potential rich source of carbon, nitrogen, and phosphorus for halophilic microorganisms. We conducted DNA growth studies for the halophilic archaeon Haloferax volcanii DS2 and show that this model Halobacteriales strain is capable of using exogenous double-stranded DNA as a nutrient. Further experiments with varying medium composition, DNA concentration, and DNA types revealed that DNA is utilized primarily as a phosphorus source, that growth on DNA is concentration-dependent, and that DNA isolated from different sources is metabolized selectively, with a bias against highly divergent methylated DNA. Additionally, fluorescence microscopy showed that labeled DNA co-localized with H. volcanii cells. The gene Hvo_1477 was also identified using a comparative genomic approach as a factor likely to be involved in DNA processing at the cell surface, and deletion of Hvo_1477 created a strain deficient in the ability to grow on extracellular DNA. Widespread distribution of Hvo_1477 homologs in archaea suggests metabolism of extracellular DNA may be of broad ecological and physiological relevance in this domain of life.

Cytochrome aa(3) in Haloferax volcanii.

Project description:A cytochrome in an extremely halophilic archaeon, Haloferax volcanii, was purified to homogeneity. This protein displayed a redox difference spectrum that is characteristic of a-type cytochromes and a CN(-) complex spectrum that indicates the presence of heme a and heme a(3). This cytochrome aa(3) consisted of 44- and 35-kDa subunits. The amino acid sequence of the 44-kDa subunit was similar to that of the heme-copper oxidase subunit I, and critical amino acid residues for metal binding, such as histidines, were highly conserved. The reduced cytochrome c partially purified from the bacterial membrane fraction was oxidized by the cytochrome aa(3), providing physiological evidence for electron transfer from cytochrome c to cytochrome aa(3) in archaea.
