NMR studies of the interactions of SpoIIAA with its partner proteins that regulate sporulation in Bacillus subtilis

Autor: J, Clarkson, I D, Campbell, M D, Yudkin

Publikováno v: Journal of molecular biology. 314(3)

SpoIIAA is a key component in the network of interactions that regulate the first sporulation-specific transcription factor, sigma(F), in Bacillus subtilis. In its unphosphorylated form SpoIIAA is either phosphorylated by or forms a non-covalent comp

Bacillus subtilis mutations that alter the pathway of phosphorylation of the anti-anti-sigmaF factor SpoIIAA lead to a Spo- phenotype

Autor: C S, Lee, J, Clarkson, J C, Shu, I D, Campbell, M D, Yudkin

Publikováno v: Molecular microbiology. 40(1)

Sigma-F, the first sporulation-specific transcription factor of Bacillus subtilis, is regulated by an anti-sigma factor SpoIIAB, which can also act as a protein kinase that phosphorylates the anti-anti-sigma factor SpoIIAA. The time course of phospho

Nucleotide Sequence of the Bacillus licheniformis Homologue of the Sporulation Locus spoIIA of Bacillus subtilis

Autor: L. Appleby, M. D. Yudkin, A. J. Smith

Publikováno v: Microbiology. 135:767-775

SUMMARY: The spoIIA locus of Bacillus licheniformis was cloned into the phage vectorφ105J9; selection was based on the ability of the clone to complement mutations in both the first and the last of the spoIIA genes of B. subtilis. The B. licheniform

Unstable mutations that relieve catabolite repression of tryptophanase synthesis by Escherichia coli

Autor: M D Yudkin

Publikováno v: Journal of Bacteriology. 130:57-61

From strains of Escherichia coli that carry deletions of the trp region, five different mutants were isolated that were capable of synthesizing tryptophanase at unusually high rates in conditions of severe catabolite repression. Notwithstanding the c

Complementation Analysis of Eleven Tryptophanase Mutations in Escherichia coli

Autor: M. K. White, M. D. Yudkin

Publikováno v: Journal of General Microbiology. 114:471-475

Summary: Nine independent mutants deficient in tryptophanase activity were isolated. Each mutation was transferred to a specialized transducing phage that carries the tryptophanase region of the Escherichia coli chromosome. The nine phages thus produ

The effect of mutations in spoOA or spoIIA on the pattern of protein synthesis in Bacillus subtilis under sporulation conditions

Autor: Hassia Boschwitz, M. D. Yudkin, Alex Keynan

Publikováno v: Molecular and General Genetics MGG. 187:244-247

By labelling wild-type Bacillus subtilis for 5 min with [35S]-methionine either at the time of resuspension in starvation medium or 1, 2 or 3 h later, and subjecting cell extracts to two-dimensional gel electrophoresis, Yudkin et al. (J. Gen. Microbi

Changes in the Pattern of Protein Synthesis During the First Three Hours of Sporculation in Bacillus subtilis

Autor: Y Hassia Boschwitz, A. Keynan, Yahli Lorch, M. D. Yudkin

Publikováno v: Microbiology. 128:2165-2177

Summary: Cultures were labelled with l-[35S]methionine for 5 min periods immediately after resuspension in sporulation medium (t 0) or at hourly intervals thereafter (t 1, t 2 or t 3). Cells were harvested and lysed very rapidly at low temperature in

Characterization of Lambda cysB and of Two Derivatives Carrying cysB Amber Mutations

Autor: M. D. Yudkin, D. M. Mascarenhas

Publikováno v: Microbiology. 118:405-410

The specialized transducing phage lambda cysB (Borck et al., 1976) was found to carry about 5 kilobases of Escherichia coli DNA. It was shown to have an intact cysB gene but none of the known neighbouring genetic loci. The phage (which is known to be

Structure and Function in a Bacillus subtilis Sporulation-specific Sigma Factor: Molecular Nature of Mutations in spoIIAC

Autor: M. D. Yudkin

Publikováno v: Microbiology. 133:475-481

SUMMARY: The spoIIAC gene was cloned from chromosomal DNA of seven spoIIAC mutants of Bacillus subtilis, and the complete sequence of the gene was determined for each mutant. Three of the mutants proved to have chain-terminating mutations (one of whi
