Coupling efficiency of secondary active transporters
2019, Current Opinion in BiotechnologyCitation Excerpt :Another strategy to avoid toxic solute levels is by introduction of a transmembrane leak pathway that permits efflux when the intracellular concentration becomes too high [49]. Indeed, a reduction in steady-state accumulation ratio ([solute]in/[solute]out) with increasing extracellular substrate concentration is well-documented, including for E. coli transport of thiogalactosides [50,51] and arabinose [52], hexose uptake in the eukaryotic Chlorella vulgaris [53], sugar transport in Streptococcus thermophilus [54], for maltose in yeast membrane vesicles [55], and for some amino acids in yeast [49] and cancerous mouse cells [56,57]. We distinguish between two types of leak pathways: those mediated by the transporter in question, termed ‘internal leaks’, and those that are not, or ‘external leaks’.
The transport and mediation mechanisms of the common sugars in Escherichia coli
2014, Biotechnology AdvancesCitation Excerpt :This regulation system is similar to that of d-xylose; this system is regulated by the cAMP receptor protein (Crp) and by AraC (Casadaban, 1976; Hendrickson and Schleif, 1984; Kolodrubetz and Schleif, 1981b; Madar et al., 2011; Schleif, 2000; Zhang and Schleif, 1996,1998). AraC regulates araBAD, araE and araFGH at the transcription level (Brown and Hogg, 1972; Casadaban, 1976; Kolodrubetz and Schleif, 1981b), and l-arabinose acts as the inducer to this system (Doyle et al., 1972; Novotnoy and Englesberg, 1966). When arabinose is in media without glucose, Crp, in the presence of cyclic AMP, stimulates PC to express AraC (Madar et al., 2011; Ogden et al., 1980).

2009, Journal of Bioscience and BioengineeringImpact of the cold shock phenomenon on quantification of intracellular metabolites in bacteria
2004, Analytical BiochemistryCitation Excerpt :Accordingly, conclusions on metabolic regulation, which rely on quantitative metabolic data, might be severely affected. The fact that cold shock effects are described in the literature for other bacteria also [9–13], suggest that this phenomenon might be important in metabolic profiling not only for C. glutamicum but also for other organisms. The filtration method without quenching presented here is an interesting approach to extract intracellular metabolites.
