Miteva V, Brenchley J. Detection and isolation of ultrasmall microorganisms from a 120,000-year-old Greenland glacier ice core. Appl Environ Microbiol. 2005;71:7806-18 pubmed
..Our filtration-cultivation procedure, combined with long incubations, enriched for novel ultrasmall-cell isolates, which is useful for studies of their metabolic properties and mechanisms for long-term survival under extreme conditions. ..
Yakhnin A, Babitzke P. Mechanism of NusG-stimulated pausing, hairpin-dependent pause site selection and intrinsic termination at overlapping pause and termination sites in the Bacillus subtilis trp leader. Mol Microbiol. 2010;76:690-705 pubmed publisher
..NusA was found to increase both pausing and termination by reducing the rate of transcription. We also found that NusG-stimulated pausing is sequence specific and that NusG does not affect termination. ..

. A metagenomic survey of microbes in honey bee colony collapse disorder. Science. 2007;318:283-7 pubmed
..One organism, Israeli acute paralysis virus of bees, was strongly correlated with CCD. ..
Xing D, Cheng S, Logan B, Regan J. Isolation of the exoelectrogenic denitrifying bacterium Comamonas denitrificans based on dilution to extinction. Appl Microbiol Biotechnol. 2010;85:1575-87 pubmed publisher
..Power generation by the facultative C. denitrificans depends on oxygen and MFC configuration, suggesting that a switch of metabolic pathway occurs for extracellular electron transfer by this denitrifying bacterium...
Maupin Furlow J, Ferry J. Characterization of the cdhD and cdhE genes encoding subunits of the corrinoid/iron-sulfur enzyme of the CO dehydrogenase complex from Methanosarcina thermophila. J Bacteriol. 1996;178:340-6 pubmed
..The purified CdhE protein exhibited an Fe-S center and base-off cobalamin binding in which the benzimidazole base nitrogen atom was no longer a lower axial ligand to the cobalt atom...
Maupin Furlow J, Ferry J. Analysis of the CO dehydrogenase/acetyl-coenzyme A synthase operon of Methanosarcina thermophila. J Bacteriol. 1996;178:6849-56 pubmed
..thermophila. The deduced protein sequence of ORF1, located between the cdhC and cdhD genes, has 29% identity to NifH2 from Methanobacterium ivanovii...
Hong S, Tran Q, Keiler K. Cell cycle-regulated degradation of tmRNA is controlled by RNase R and SmpB. Mol Microbiol. 2005;57:565-75 pubmed publisher
..This model explains the regulation of SsrA RNA in other bacteria, and suggests that a highly conserved regulatory mechanism controls SsrA activity...
Dubey A, Baker C, Romeo T, Babitzke P. RNA sequence and secondary structure participate in high-affinity CsrA-RNA interaction. RNA. 2005;11:1579-87 pubmed
..A mutational analysis of one selected ligand confirmed that the conserved ACA, GGA, and GU residues were critical for CsrA binding and that RNA secondary structure participates in CsrA-RNA recognition. ..
Hong S, Lessner F, Mahen E, Keiler K. Proteomic identification of tmRNA substrates. Proc Natl Acad Sci U S A. 2007;104:17128-33 pubmed
..Analysis of the tagging sites within these substrates revealed a conserved nucleotide motif 5' of the tagging site, which is required for wild-type tmRNA tagging...
