The RNA degradosome is a multi-enzyme assembly that contributes to key processes of RNA metabolism, and it engages numerous partners in serving its varied functional roles. Small domains within the assembly recognize collectively a diverse range of macromolecules, including the core protein components, the cytoplasmic lipid membrane, mRNAs, non-coding(More)
UNLABELLED Polyurethane (PU) is widely used in many aspects of modern life because of its versatility and resistance. However, PU waste disposal generates large problems, since it is slowly degraded, there are limited recycling processes, and its destruction may generate toxic compounds. In this work, we isolated fungal strains able to grow in mineral(More)
We report an analysis in vivo of the RNA degradosome assembly of Escherichia coli. Employing fluorescence microscopy imaging and fluorescence energy transfer (FRET) measurements, we present evidence for in vivo pairwise interactions between RNase E-PNPase (polynucleotide phosphorylase), and RNase E-Enolase. These interactions are absent in a mutant strain(More)
Greater Mexico City is one of the largest urban centers in the world, with an estimated population by 2010 of more than 20 million inhabitants. In urban areas like this, biological material is present at all atmospheric levels including live bacteria. We sampled the low atmosphere in several surveys at different points by the gravity method on LB and blood(More)
The original published version of this article has some imprecisions in the coordinates for the forward and reverse primers in 16S rDNA molecule, B16S rDNA Libraries^ of the BMaterials and Methods^ section (Page no. 76). The correct version is presented below: The seven forward primers used in this work, V3-341F2, V3341F4, V3-341F7, V3-341F8, V3-341F9,(More)
The molecular mechanisms underlying the biodegradation of N-methylpyrrolidone (NMP), a widely used industrial solvent that produces skin irritation in humans and is teratogenic in rats, are unknown. Alicycliphilus sp. strain BQ1 degrades NMP. By studying a transposon-tagged mutant unable to degrade NMP, we identified a six-gene cluster (nmpABCDEF) that is(More)
