The naming of the genetic elements involved in the control of transcription has presented
problems which we feel call for a modification of the accepted system of nomenclature. The …

Publisher Summary This chapter discusses the importance of the mechanism of permeation
of nucleosides, nucleobases, and nucleotides through the cell membranes of eukaryotes …

Tsx is a nucleoside‐specific outer membrane (OM) transporter of Gram‐negative bacteria.
We present crystal structures of Escherichia coli Tsx in the absence and presence of …

The effect of a number of adrenergic receptor agonists and antagonists on the growth of
Escherichia coli and Yersinia enterocolitica was examined in order to delineate possible …

The Tsx protein from the outer membrane of Escherichia coli is known to be involved in the
permeation of nucleosides across the outer membrane under limiting substrate conditions …

Nucleoside triphosphates play a central role in biology, but efforts to study these roles have
proven difficult because the levels of triphosphates are tightly regulated in a cell and …

We have investigated the possibility of a fixed terminus for bidirectional replication in
Escherichia coli by determining whether a displacement of the chromosome replication …

The surface of a gram-negative bacterium is made up of the lipopolysaccharide (lps) and
protein components of the outer leaflet of its outer membrane, and of capsular …

Osmotic shock treatment of cells of Escherichia coli K12 caused a reduction in the transport
of nucleosides into the cells. The strains used carried mutations in the nucleoside …

(1) The influence of caffeine on growth and on the metabolism of thymidine was investigated
in various E. coli strains. Caffeine caused filamentous growth in all strains investigated. The …
