Dual Regulation of Bacillus subtilis kinB Gene Encoding a Sporulation Trigger by SinR through Transcription Repression and Positive Stringent Transcription Control

Autor: Yasutaro Fujita, Mitsuo Ogura, Satomi Nii, Kazutake Hirooka

Publikováno v: Frontiers in Microbiology, Vol 8 (2017)

It is known that transcription of kinB encoding a trigger for Bacillus subtilis sporulation is under repression by SinR, a master repressor of biofilm formation, and under positive stringent transcription control depending on the adenine species at t

RhgKL and CcpA directly regulate the rhiLFGN-rhgR-yesTUV operon involved in the metabolism of rhamnogalacturonan type I in Bacillus subtilis

Autor: Kazutake Hirooka

Publikováno v: Bioscience, biotechnology, and biochemistry. 86(10)

The Bacillus subtilis rhiLFGN-rhgR-yesTUVWXYZ (formerly yesOPQRSTUVWXYZ) gene cluster includes genes for metabolizing rhamnogalacturonan type I (RG-I), a major pectin constituent, and the rhgR gene encoding an AraC/XylS transcriptional activator. The

Identification of critical residues for the catalytic activity of ComQ, a Bacillus prenylation enzyme for quorum sensing, by using a simple bioassay system

Autor: Masahiro Okada, Saki Shioda, Kazutake Hirooka

Bacillus ComQ participates in the biosynthesis of a quorum-sensing signaling molecule (ComX pheromone) through catalyzing the prenylation at a Trp residue of the precursor peptide (pre-ComX) with geranyl diphosphate (C10 type) or farnesyl diphosphate

CcpA-Mediated Catabolite Activation of the Bacillus subtilis ilv-leu Operon and Its Negation by Either CodY- or TnrA-Mediated Negative Regulation

Autor: Shigeo Tojo, Yasutaro Fujita, Takenori Satomura, Kazutake Hirooka

Publikováno v: Journal of Bacteriology. 196:3793-3806

The Bacillus subtilis ilv-leu operon functions in the biosynthesis of branched-chain amino acids. It undergoes catabolite activation involving a promoter-proximal cre which is mediated by the complex of CcpA and P-Ser-HPr. This activation of ilv-leu

Structural Insights into the Low pH Adaptation of a Unique Carboxylesterase from Ferroplasma

Autor: Toru Nakayama, Satoshi Yamashita, Naoto Fujino, Kazutake Hirooka, Miho Hosoya, Masami Kusunoki, Kazuhiro Ohara, Seiji Takahashi, Hideaki Unno, Yasuhiro Oshima

Publikováno v: Journal of Biological Chemistry. 289:24499-24510

To investigate the mechanism for low pH adaptation by a carboxylesterase, structural and biochemical analyses of EstFa_R (a recombinant, slightly acidophilic carboxylesterase from Ferroplasma acidiphilum) and SshEstI (an alkaliphilic carboxylesterase

Regulation of the rhaEWRBMA Operon Involved in l-Rhamnose Catabolism through Two Transcriptional Factors, RhaR and CcpA, in Bacillus subtilis

Autor: Kazutake Hirooka, Takenori Satomura, Yusuke Kodoi, Yasutaro Fujita

The Bacillus subtilis rhaEWRBMA (formerly yuxG-yulBCDE ) operon consists of four genes encoding enzymes for l -rhamnose catabolism and the rhaR gene encoding a DeoR-type transcriptional regulator. DNase I footprinting analysis showed that the RhaR pr
