A functional Spo0A is required for maximal aprE expression in Bacillus subtilis

FEBS Letters, 1996
The initiation of sporulation in Bacillus subtilis is under control of the transcriptional factor SpoOA. Most SpoOA mutants fail to initiate the sporulation process and all the sporulation initiated processes such as the synthesis of subtilisin. However, the product of spoOA9V, one of the several spoOA mutants characterized, distinguishes itself in the

Principle of DNA recognition by sporulation-regulatory protein (Spo0A) in Bacillus subtilis

, 2019
Master sporulation-regulatory protein Spo0A binds to the cognate DNA sequence 5′-TGTCGAA-3′ (0 A-box) and control transcription of hundreds of genes in sporulating Bacilli.

Spo0a: Más allá de la esporulación en Bacillus [PDF]

, 2019
Cuando hablamos de supervivencia entre bacterias, uno de los mejores ejemplos es la bacteria del suelo Bacillus subtilis. Esta bacteria es capaz de hacer frente a situaciones extremas en cuanto a nutrientes y condiciones ambientales.

Bacillus can be induced to sporulate through expression of a constitutively active allele of Spo0A (Spo0A*) if induced during stationary phase or grown in conditioned media.

, 2015
(A) A strain harboring Phy-spank—Spo0A* (MF2146) was grown in CH at 37°C, induced by the addition of IPTG (200 μM) at the indicated optical densities, and grown for 2 hrs at 37°C before image capture.

The impact of orphan histidine kinases and phosphotransfer proteins on the regulation of clostridial sporulation initiation

mBio
Sporulation is an important feature of the clostridial life cycle, facilitating survival of these bacteria in harsh environments, contributing to disease transmission for pathogenic species, and sharing common early steps that are also involved in ...

The Spo0A regulon of Bacillus subtilis.

, 2003
International audienceThe master regulator for entry into sporulation in Bacillus subtilis is the DNA-binding protein Spo0A, which has been found to influence, directly or indirectly, the expression of over 500 genes during the early stages of ...

Phosphorylation of the Bacillus subtilis Replication Controller YabA Plays a Role in Regulation of Sporulation and Biofilm Formation

Frontiers in Microbiology, 2018
Bacillus subtilis cells can adopt different life-styles in response to various environmental cues, including planktonic cells during vegetative growth, sessile cells during biofilm formation and sporulation.

botA- ja spo0A-geenien toiminnan tutkiminen Clostridium botulinum ATCC 19397 -kannassa CRISPR-Cas9–menetelmän avulla

, 2020
Clostridium botulinum on anaerobinen bakteeri, joka tuottaa vahvinta luonnollista myrkkyä, botuliinineurotoksiinia. Botuliinitoksiini aiheuttaa ihmisille ja eläimille botulismina tunnettua velttohalvausta, joka voi johtaa kuolemaan. C.
