Sodium-dependent silicate transport in the apochlorotic marine diatom Nitzschia alba.
Bhattacharyya P, Volcani BE. Bhattacharyya P, et al. Proc Natl Acad Sci U S A. 1980 Nov;77(11):6386-90. doi: 10.1073/pnas.77.11.6386. Proc Natl Acad Sci U S A. 1980. PMID: 16592914 Free PMC article.
In isolated membrane vesicles, silicate is taken up when a Na(+) gradient is imposed across the membrane or is generated by cytoplasmic Na(+),K(+)-ATPase. H(+) or K(+) gradients in either direction do not stimulate uptake. ...The vesicular uptake shows saturation ki …

Ligand binding and protein dynamics in neuroglobin.
Kriegl JM, Bhattacharyya AJ, Nienhaus K, Deng P, Minkow O, Nienhaus GU. Kriegl JM, et al. Proc Natl Acad Sci U S A. 2002 Jun 11;99(12):7992-7. doi: 10.1073/pnas.082244399. Epub 2002 Jun 4. Proc Natl Acad Sci U S A. 2002. PMID: 12048231 Free PMC article.
By using infrared spectroscopy and nanosecond time-resolved visible spectroscopy, we have investigated the ligand-binding reaction over a wide temperature range (3-353 K). Multiple, intrinsically heterogeneous distal heme pocket conformations exist in NgbCO. ...The photodi …

polyglutamine aggregation nucleation: thermodynamics of a highly unfavorable protein folding reaction.
Bhattacharyya AM, Thakur AK, Wetzel R. Bhattacharyya AM, et al. Proc Natl Acad Sci U S A. 2005 Oct 25;102(43):15400-5. doi: 10.1073/pnas.0501651102. Epub 2005 Oct 17. Proc Natl Acad Sci U S A. 2005. PMID: 16230628 Free PMC article.
We find that, for the polyGln peptide Q(47), the second-order rate constant for fibril elongation is 11,400 liters/mol per s, whereas K(n*)), the equilibrium constant for nucleation of aggregation, is remarkably small, equal to 2.6 x 10(-9). ...

Interaction of aurintricarboxylic acid (ATA) with four nucleic acid binding proteins DNase I, RNase A, reverse transcriptase and Taq polymerase.
Ghosh U, Giri K, Bhattacharyya NP. Ghosh U, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2009 Dec;74(5):1145-51. doi: 10.1016/j.saa.2009.09.024. Epub 2009 Sep 19. Spectrochim Acta A Mol Biomol Spectrosc. 2009. PMID: 19836295 Free PMC article.
As the telomerase reverse transcriptase (TERT) is the main catalytic subunit of telomerase holoenzyme, we also monitored effect of ATA on telomerase activity in vivo and observed dose-dependent inhibition of telomerase activity in Chinese hamster V79 cells treated with ATA. Direc …

Adiabatic eigenfunction based approach to coherent transfer: application to the Fenna-Matthews-Olson (FMO) complex and the role of correlations in the efficiency of energy transfer.
Bhattacharyya P, Sebastian KL. Bhattacharyya P, et al. J Phys Chem A. 2013 Sep 12;117(36):8806-13. doi: 10.1021/jp4045463. Epub 2013 Jul 9. J Phys Chem A. 2013. PMID: 23805909
We have recently suggested a method (Pallavi Bhattacharyya and K. L. Sebastian, Physical Review E 2013, 87, 062712) for the analysis of coherence in finite-level systems that are coupled to the surroundings and used it to study the process of energy transfer in the …

Temperature dependence of anisotropy decay and solvation dynamics of coumarin 153 in gamma-cyclodextrin aggregates.
Roy D, Mondal SK, Sahu K, Ghosh S, Sen P, Bhattacharyya K. Roy D, et al. J Phys Chem A. 2005 Aug 25;109(33):7359-64. doi: 10.1021/jp0520143. J Phys Chem A. 2005. PMID: 16834102
In these aggregates with rise in temperature, the average solvation time ((obs)) decreases markedly from 680 ps at 278 K to 160 ps at 318 K. The dynamic Stokes shift is found to decrease from 800 cm(-1) at 278 K to 250 cm(-1) at 318 K. .. …

Valinomycin-induced uptake of potassium in membrane vesicles from Escherichia coli.
Bhattacharyya P, Epstein W, Silver S. Bhattacharyya P, et al. Proc Natl Acad Sci U S A. 1971 Jul;68(7):1488-92. doi: 10.1073/pnas.68.7.1488. Proc Natl Acad Sci U S A. 1971. PMID: 4934520 Free PMC article.
The addition of valinomycin to the membrane ghosts restores the capacity to accumulate radioactive (42)K and (86)Rb by a temperature- and energy-dependent process. Membrane vesicles prepared from mutants of E. coli altered in potassium transport show defects in the valinom …
