… 7, changing the T at position −85 to a G in the C6706 promoter fragment had no effect on …
Influence of the C6706 G-77T change on virulence gene expression As the G-77T change in …

We describe here a new member of the LysR family of transcriptional regulators, AphB, which
is required for activation of the Vibrio cholerae ToxR virulence cascade. AphB activates the …

… The A at −65 that is critical for transcriptional activation by AphB lies within the dyad, and
the presence of a G in this position in the El Tor promoter disrupts the symmetry of the site. …

… Citation55 In a placebo-controlled double-blind study of OCD, Citation56 24 subjects
were assigned glycine 60 g/day or placebo. Glycine noncompliance, partly due a lack of …

… A missense mutation of an A 266 G in the coding region, resulting in an amino acid change
from asparagine to serine (N 89 S), was found in Bgd3, Bgd4, Bgd5, Bgd6, MQ1795, MQ04, …

AphB is a LysR-type activator that initiates the expression of the virulence cascade in Vibrio
cholerae by cooperating with the quorum-sensing-regulated activator AphA at the tcpPH …

… Sequencing of the resulting products revealed that the transcriptional start of alsD is an A
27 bp upstream of its ATG and that of alsR is either an A or a G 33–34 bp upstream of its ATG (…

… Sequencing of the major resulting PCR product revealed a transcriptional start site (G) 93 nt
… of it revealed a second transcriptional start site (G or C) 309 to 310 nt upstream of the ATG …

… naturally occurring G-77T change … Kovacikova and Skorupski, 2002a) because in both of
these strains, HapR is unable to repress the aphA promoter. However, the Δlrp mutation in the G…

… Unlike H-NS, IHF recognizes a specific asymmetric site on DNA, the 13-bp consensus
target sequence WATCAANNNNTTR, where W represents A or T and R represents A or G (10). …
