Research Article 13: Cell-Free Studies on the Regulation of the lac Operon INTRODUCTION The ideal test for a model of gene regulation would be the measurement of gene activity as a function of the concentration of each of the alleged regulating components. A cell-free system in which it would...
Presents information on a study which cloned and sequenced the promoter-proximal region of the Bacillus subtilis operon containing the pbpB gene. Encoding of essential penicillin-binding protein PBP2B; Types of bacterial strains, plasmids, synthetic oligonucleotides, and phages used in study; ...
Finally, the neighborhood on chromosome X (see "Neural", Figure 3) consists of genes most highly expressed in neural tissue and is formed by at least three different gene duplications: Bex1 and Bex2 are duplicates with Ngfrap1 highly similar (BLASTP e-value 8x10-7); Gprasp1, Gprasp2,...
We isolated from a Salmonella typhimurium rfaH suppressor strain a gene that complements in trans the attenuated transcription of the hlyCABD hemolysin operon caused by an rfaH mutation. The gene is homologous to the uncharacterised Escherichia coli gene yaeQ . YaeQ did not increase hlyCABD -...
The resulting genome consists of one chromosome (6.48 Mb) and eight plasmids ranging from 10,690 bp to 220,129 bp in size (Fig. 1b, Supplementary Fig. S1). The putative magnetosome genes localize within a single region (27.5 kb) on the chromosome, compactly organized in four...
The mec gene complex consists of mecA, the regulatory genes and associated insertion sequences and has been classified into six different classes, i.e. A, B, C1, C2, D and E. Cassette chromosome recombinase (ccr) genes (ccrC or the pair of ccrA and ccrB) encode recombinases mediating ...
The DNA sequence determination or the ƒ1 operon between the genes encoding the F1 subunit (caf1) and chaperone-like protein (caf1M) revealed a large open reading frame that codes for a polypeptide similar to some E. coli proteins involved in the biogenesis of fimbria. The deletion and in...
(Extended Data Fig.1a). This system consists of a two-gene operon harbouring a Cdn belonging to the E clade, cluster 38(Ssc-CdnE03) and a transmembrane effector, Cap15, which was recently demonstrated to limit phage propagation by disrupting the host membrane23. Since we were unable to ...
