Abstract

Determining the functional activity of an essential RNA in vivo presents special challenges. We have devised an in vivo analysis of alternative forms of an essential tRNA gene in Escherichia coli knockout cells using either a plasmid switch or a regulated two-plasmid system. The model system is presented together with a description of the new plasmids and procedures necessary to effect these analyses. The system is readily adaptable to non-essential RNAs.

Development of an arabinose-inducible gene expression system for nontuberculous mycobacteria.

Nontuberculous mycobacteria (NTM) are emerging pathogens for which genetic tools remain limited. Here, we developed an arabinose-inducible gene expression system based on a modified pBAD24 vector adapted for mycobacterial hosts. The vector carries replication origins for mycobacteria and Escherichia coli, as well as selectable markers compatible with NTM. In Mycobacterium abscessus (Mycobacteroides abscessus), the system enabled dose-dependent induction of target gene expression by arabinose, as demonstrated by increased antibiotic resistance and quantitative RT-PCR analysis. Although basal expression was observed in the absence of arabinose, expression levels were tunable across arabinose concentrations. The system was also functional in Mycobacterium smegmatis (Mycolicibacterium smegmatis) and Mycobacterium bovis BCG, although the degree of basal expression varied among host species. These results establish a tunable inducible expression system for mycobacteria and provide a useful genetic tool for studies of NTM biology.

Production of D-tagatose at high temperatures using immobilized Escherichia coli cells expressing L-arabinose isomerase from Thermotoga neapolitana.

Escherichia coli cells expressing L-arabinose isomerase from Thermotoga neapolitana (TNAI) were immobilized in calcium alginate beads. The resulting cell reactor (2.4 U, t (1/2) = 43 days at 70 degrees C) in a continuous recycling mode at 70 degrees C produced 49 and 38 g D-tagatose/l from 180 and 90 g D-galactose/l, respectively, within 12 h.

Genetic analysis of a novel pathway for D-xylose metabolism in Caulobacter crescentus.

Genetic data suggest that the oligotrophic freshwater bacterium Caulobacter crescentus metabolizes D-xylose through a pathway yielding alpha-ketoglutarate, comparable to the recently described L-arabinose degradation pathway of Azospirillum brasilense. Enzymes of the C. crescentus pathway, including an NAD(+)-dependent xylose dehydrogenase, are encoded in the xylose-inducible xylXABCD operon (CC0823-CC0819).
