Isolation and characterization of new pterins from nonmethanogenic archaebacteria
… discovered in halophilic and thermoacidophilic archaebacteria. Two of these were identified in the extreme halophiles and were thus called halopterins. One of these halopterins is produced by Halobacterium salinarium, Halobacterium halobium, and Halococcus morrhuae and is called …

Structural Characterization of the Transfer Ribonucleic Acids From Halobacterium Volcanii and Other Archaebacteria
The archaebacteria have been defined primarily on the basis of their ribosomal RNAs, as a primary kingdom, distinct from the eubacteria ('prokaryotes') and the eucaryotes. To help in evaluating the molecular affinities, we characterize here the transfer RNAs (tRNAs) in two ways. First, we describe …

Phylogenetic Relationships of Thermophilic Bacteria
… of prokaryotic descent--the eubacteria and the archaebacteria. The phylogenetic relationships of several new isolates of extremely thermophilic bacteria have been determined and used to gain a deeper understanding of the role of thermophilic bacteria in early evolution. The 16S and 23S ribosomal …

The organization, expression, function and evolution of some essential genes from the hyperthermophilic eubacterium thermotoga maritima
… proteins L11, L1,L10 and L12 from eubacteria, archaebacteria and eukaryotes have been aligned, and the alignments were subjected to quantitative phylogenetic analysis. Eubacteria andeukaryotes each form a well-defined, coherent and non-overlapping group. Archaebacteria also form a coherent …

Developing and applying supertree methods in Phylogenomics and Macroevolution
… phylogeny of the Eubacteria and the Archaebacteria. These new SMs are discussed, with reference to other, well-‐ known SMs like Matrix Representation with Parsimony. Both the ML and Bayesian SM offer multiple attractive advantages over current alternatives.

Characterization of Ortho-Succinylbenzoate Synthase (Osbs): A Study of Mechanism, Proficiency and Evolutionary Diversity
… electron acceptor that is utilized in bacteria, archaebacteria and red green algae. OSBSs from over 70 organisms have been identified and their pairwise sequence homology is often as low as 14%. The sequence divergence has allowed us to explore enzymes with different sequences that catalyze the …

Investigations on the taxonomy and the genetics of caldoactive bacteria
… Wolf and Sharp (1981). Analysis of a number of archaebacteria confirmed the unique nature of AN1 isolated from a New Zealand hot spring by Morgan and Daniels (1982). The Thermoproteus-type strains isolated from New Zealand seem rather different from the type strain T. tenax which also has some …

Arginase from Bacillus caldovelox
… Bacillus species, six extremely thermophilic archaebacteria and other thermophilic bacteria were cultured in arginine-supplemented media and screened for arginase, arginine deiminase and arginine decarboxylase activity by a reversed-phase liquid chromatography method developed to detect these …

Biosynthesis of Caldariellaquinone in Sulfolobus acidocaldarius
… from methionine to cysteine occurring in archaebacteria.
