TLDR
The drastic down effect of base substitutions in the TGGCAC, TTGCA consensus sequence on the expression of the levanase operon confirmed the involvement of the "-12, -24" region in promoter function and the isolation and characterization of eight mutations in the UAS region confirmed the importance of the palindromic structure in promoter activation.

Genetic regulation of nitrogen fixation in rhizobia.

TL;DR: Although the involvement of FixLJ and FixK in nifA regulation is remarkably different in the three rhizobial species discussed here, they constitute a regulatory cascade that uniformly controls the expression of genes (fixNOQP) encoding a distinct cytochrome oxidase complex probably required for bacterial respiration under low-oxygen conditions.

Regulation of carbon catabolism in Bacillus species.

TL;DR: The gram-positive bacterium Bacillus subtilisis capable of using numerous carbohydrates as single sources of carbon and energy is discussed, with antitermination apparently more common in B. subtil is than in other bacteria.
Journal ArticleDOI

Compilation and analysis of sigma(54)-dependent promoter sequences.

TL;DR: The use of the extended consensus increases the probability of identifying genuine -24/-12 promoters and the effect of several reported mutations on RNA-polymerase binding and promoter strength is discussed in the light of the updated consensus.

The Bacillus subtilis crh gene encodes a HPr-like protein involved in carbon catabolite repression

TL;DR: The results suggest that CCR of certain catabolic operons requires, in addition to CcpA, ATP-dependent phosphorylation of Crh, and HPr at Ser-46, as well as the discovery of a new B. subtilis gene encoding a HPr-like protein, Crh (for catabolite repression HPr).
Journal ArticleDOI

Fermentative metabolism of Bacillus subtilis: physiology and regulation of gene expression.

TL;DR: In agreement with its known aerobic function, no obvious oxygen- or nitrate-dependent pta regulation was observed and a model for the regulation of the anaerobic fermentation genes in B. subtilis is proposed.

DNA sequencing with chain-terminating inhibitors

TL;DR: A new method for determining nucleotide sequences in DNA is described, which makes use of the 2',3'-dideoxy and arabinon nucleoside analogues of the normal deoxynucleoside triphosphates, which act as specific chain-terminating inhibitors of DNA polymerase.
Journal ArticleDOI

Rapid and efficient site-specific mutagenesis without phenotypic selection.

TL;DR: The high efficiency, approximately equal to 10-fold greater than that observed using current methods without enrichment procedures, is obtained by using a DNA template containing several uracil residues in place of thymine, which is applied to mutations introduced via both oligonucleotides and error-prone polymerization.
Book ChapterDOI

Specific synthesis of DNA in vitro via a polymerase-catalyzed chain reaction.

TL;DR: A method whereby a nucleic acid sequence can be exponentially amplified in vitro is described in the chapter, and the possibility of utilizing a heat-stable DNA polymerase is explored so as to avoid the need for addition of new enzyme after each cycle of thermal denaturation.
