Single-cell measurement of the levels and distributions of the phosphorelay components in a population of sporulating Bacillus subtilis cells.
Eswaramoorthy P, Dinh J, Duan D, Igoshin OA, Fujita M. Eswaramoorthy P, et al. Microbiology (Reading). 2010 Aug;156(Pt 8):2294-2304. doi: 10.1099/mic.0.038497-0. Epub 2010 Apr 22. Microbiology (Reading). 2010. PMID: 20413551 Free article.
The phosphorylated kinase transfers the phosphate group to Spo0A via the phosphorelay and thus triggers sporulation. With a combination of quantitative immunoblot analysis, microscopy imaging and computational analysis, here we found that each of the phosphorelay component …

Asymmetric division and differential gene expression during a bacterial developmental program requires DivIVA.
Eswaramoorthy P, Winter PW, Wawrzusin P, York AG, Shroff H, Ramamurthi KS. Eswaramoorthy P, et al. PLoS Genet. 2014 Aug 7;10(8):e1004526. doi: 10.1371/journal.pgen.1004526. eCollection 2014 Aug. PLoS Genet. 2014. PMID: 25101664 Free PMC article.
Sporulation in the bacterium Bacillus subtilis is a developmental program in which a progenitor cell differentiates into two different cell types, the smaller of which eventually becomes a dormant cell called a spore. ...Here, we show that the structural protein DivIVA loc …

The threshold level of the sensor histidine kinase KinA governs entry into sporulation in Bacillus subtilis.
Eswaramoorthy P, Duan D, Dinh J, Dravis A, Devi SN, Fujita M. Eswaramoorthy P, et al. J Bacteriol. 2010 Aug;192(15):3870-82. doi: 10.1128/JB.00466-10. Epub 2010 May 28. J Bacteriol. 2010. PMID: 20511506 Free PMC article.
Sporulation in Bacillus subtilis is controlled by a complex gene regulatory circuit that is activated upon nutrient deprivation. ...Moreover, the engineered cells expressing KinA under a sigma(H)-dependent promoter that is similar to but stronger than the endogenous kinA p …

Systematic domain deletion analysis of the major sporulation kinase in Bacillus subtilis.
Eswaramoorthy P, Fujita M. Eswaramoorthy P, et al. J Bacteriol. 2010 Mar;192(6):1744-8. doi: 10.1128/JB.01481-09. Epub 2010 Jan 15. J Bacteriol. 2010. PMID: 20081035 Free PMC article.
To characterize the role of the three PAS domains in KinA, the major sporulation kinase in Bacillus subtilis, we constructed a series of systematic PAS domain deletion mutants and analyzed their activities using an IPTG (isopropyl-beta-d-thiogalactopyranoside)-inducible ar …

Expression level of a chimeric kinase governs entry into sporulation in Bacillus subtilis.
Eswaramoorthy P, Dravis A, Devi SN, Vishnoi M, Dao HA, Fujita M. Eswaramoorthy P, et al. J Bacteriol. 2011 Nov;193(22):6113-22. doi: 10.1128/JB.05920-11. Epub 2011 Sep 16. J Bacteriol. 2011. PMID: 21926229 Free PMC article.
Upon starvation, Bacillus subtilis cells switch from growth to sporulation. It is believed that the N-terminal sensor domain of the cytoplasmic histidine kinase KinA is responsible for detection of the sporulation-specific signal(s) that appears to be produced only …

In vivo domain-based functional analysis of the major sporulation sensor kinase, KinA, in Bacillus subtilis.
Eswaramoorthy P, Guo T, Fujita M. Eswaramoorthy P, et al. J Bacteriol. 2009 Sep;191(17):5358-68. doi: 10.1128/JB.00503-09. Epub 2009 Jun 26. J Bacteriol. 2009. PMID: 19561131 Free PMC article.
In Bacillus subtilis, KinA is a major kinase providing phosphate input to the phosphorelay that activates the sporulation pathway upon starvation via the phosphorylated Spo0A transcription factor. ...Based on these results, we propose that the primary role of the amino-ter …
