Chimeric chemoreceptors in Escherichia coli: signaling properties of Tar-Tap and Tap-Tar hybrids.
The Tap (taxis toward peptides) receptor and the periplasmic dipeptide-binding protein (DBP) of Escherichia coli together mediate chemotactic responses to dipeptides. Tap is a low-abundance receptor. It is present in 5- to 10-fold-fewer copies than high-abundance receptors like Tar and Tsr. Cells expressing Tap as the sole receptor, even from a multicopy plasmid at 5- to 10-fold-overexpressed l...
متن کاملTandem affinity purification of miRNA target mRNAs (TAP-Tar)
MicroRNAs (miRNAs) bind to Argonaute proteins, and together they form the RISC complex and regulate target mRNA translation and/or stability. Identification of mRNA targets is key to deciphering the physiological functions and mode of action of miRNAs. In mammals, miRNAs are generally poorly homologous to their target sequence, and target identification cannot be based solely on bioinformatics....
متن کاملTap, tap, tap to better patient documentation.
Dr. Greg Hinson is in the minority. He's among the meager 13 percent of physicians in solo practice who use electronic medical records, according to a recent Commonwealth Fund survey. But Hinson is comfortable being apart from the madding crowd. He knew electronic record keeping would be the ticket to efficiencies in his practice so he traded in his hodgepodge of inadequate record-keeping techn...
متن کاملHappiness on Tap:
We study the demand for household water connections in urban Morocco, and the effect of such connections on household welfare. In the northern city of Tangiers, among homeowners without a private connection to the city’s water grid, a random subset was offered a simplified procedure to purchase a household connection on credit (at a zero percent interest rate). Take-up was high, at 69%. Because...
متن کاملNew focus on tar sands
By many analyses, we shall soon be approaching 'peak oil' production — the time when annual output begins to stall in the face of ever-increasing demand. Oil companies are therefore increasing efforts to locate new sources and, in the face of the large-scale environmental problems caused by the failure of a deep-drilling operation in the Gulf of Mexico, the successful development of Canada's ta...
