How can you use “arsc” in a sentence? Here are some example sentences to help you improve your vocabulary:
open reading frames (ORFs) obtained from genome projects that showed homology to known arsC genes).
The ars operon consists of a group of genes coding for a transmembrane pump and an arsenate reductase ( arsC ). The operon includes a regulatory gene ( arsR ) and a gene coding for an arsenite-specific pump ( arsB ) as well as arsC [ 13 ] . Arsenite is pumped directly out of the cell by the arsB protein; however arsenate must first be reduced to arsenite by the cytoplasmic arsenate reductase coded from arsC . Some bacteria also possess other ars genes: arsA produces an arsenite-stimulated ATPase [ 14 ] that results in more efficient arsenite extrusion; arsD encodes for a regulatory protein that controls the upper level of ars expression [ 15 ] ; arsH has been identified but has an uncertain function [ 16 ] . The ars operon was initially recognized in plamids of Staphylococcus aureus and S. xylosus [ 17 18 ] but has subsequently been found in other microorganisms (e.g.
Thus, the arsC gene, and by extension, arsenic resistance mechanisms, must have been present in early organisms, either in the last universal ancestor or after the divergence of the two prokaryotic domains (i.e.
The 16S rRNA based phylogenetic tree (Figure 1) generally matched the accepted 16S rRNA model with clear separation of the two prokaryotic domains and the subsequent divergence of Eukarya (represented by Saccharomyces cerevisiae ) from Archaea [ 31 ] . Minor inconsistencies such as Ralstonia solanacearum (β-Proteobacteria) forming a deep branch within the γ-Proteobacteria, or Fusobacterium nucleatum (Fusobacteria) and Leptospira interrogans (Spirochetes) grouping loosely with the Gram-positive Bacteria are likely the result of the limited data set used (they were the only representatives of their respective phyla that had listed arsC genes) and do not challenge established relationships.
Surprisingly, p35 showed strong binding activity in the presence of the oligo ARSb (64% AT rich), ARSc (66% AT rich) and ARSd (74% AT rich) respectively (Figure 7D).
