Phylogenomic analysis of the family Peptostreptococcaceae (Clostridium cluster XI) and proposal for reclassification of Clostridium litorale (Fendrich et al. 1991) and Eubacterium acidaminophilum (Zindel et al. 1989) as Peptoclostridium litorale gen. nov. comb. nov. and Peptoclostridium acidaminophilum comb. nov.
In 1994, analyses of clostridial 16S rRNA gene sequences led to the assignment of 18 species to Clostridium cluster XI, separating them from Clostridium sensu stricto (Clostridium cluster I). Subsequently, most cluster XI species have been assigned to the family Peptostreptococcaceae with some species being reassigned to new genera. However, several misclassified Clostridium species remained, c...
متن کاملPurification and properties of ornithine racemase from Clostridium sticklandii.
Ornithine racemase has been purified to homogeneity from Clostridium sticklandii, as shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. This is the first racemase known to be highly specific to ornithine. This PLP-dependent enzyme has an M(r) of 92, 000, with a K(m) for L-ornithine of 0.77 +/- 0.05 mM and a k(cat) of 980 +/- 20 s(-1).
متن کاملAn rRNA approach for assessing the role of obligate amino acid-fermenting bacteria in ruminal amino acid deamination.
Ruminal amino acid degradation is a nutritionally wasteful process that produces excess ruminal ammonia. Monensin inhibited the growth of monensin-sensitive, obligate amino acid-fermenting bacteria and decreased the ruminal ammonia concentrations of cattle. 16S rRNA probes indicated that monensin inhibited the growth of Peptostreptococcus anaerobius and Clostridium sticklandii in the rumen. Clo...
متن کاملSynthesis of adenine-B12 coenzyme by Clostridium sticklandii: relationship to one-carbon metabolism.
A member of the vitamin B12 group has been identified as the red chromophore of reddish brown enzyme fractions obtained from Clostridium sticklandii. An orange compound which appears to be identical with the coenzyme form of pseudovitamin B12 (or adenine-B12 coenzyme) discovered by Barker et al. (Proe. Natl. Acad. Sci. U. S., 44, 1093, 1958) is obtained if preparations are protected from visibl...
متن کاملSelenium-containing tRNAs from Clostridium sticklandii: cochromatography of one species with L-prolyl-tRNA.
75Se-Labeled tRNAs were synthesized by Clostridium sticklandii cultures supplemented with 1 microM sodium [75Se]selenite or [75Se]selenocysteine. This process is highly specific for selenium; it occurred in the presence of 1.2 mM sodium sulfide and was not decreased by the further addition of a 500-fold molar excess of cysteine. The 75Se in these tRNAs was located in the polynucleotide portion ...
