  • Allosteric Transition Induced by Mg2+ Ion in a Transactivator Monitored by SERS 
    Kundu, Partha P.; Bhowmick, Tuhin; Swapna, Ganduri; KUMAR, G. V. PAVAN; Nagaraja, Valakunja; Narayana, Chandrabhas (American Chemical Society, 2014-05)
    We demonstrate the utility of the surface-enhanced Raman spectroscopy (SERS) to monitor conformational transitions in protein upon ligand binding. The changes in protein’s secondary and tertiary structures were monitored ...
  • Structural insight into hybrid peptide epsilon-helices 
    MISRA, RAJKUMAR; George, Gijo; REJA, RAHI M.; DEY, SANJIT; Raghothama, Srinivasarao; GOPI, HOSAHUDYA N. (Royal Society of Chemistry, 2020-02)
    Unique ε-helical organizations (11-helices) from β,γ-hybrid peptides composed of chiral β3-amino acids along with achiral 3,3- or 4,4-dimethyl substituted γ-amino acids are disclosed.
  • Effect of a single water molecule on the conformational preferences of a capped Pro-Gly dipeptide in the gas phase 
    MANDAL, SOURAV; Kossov, Arsene; Carcabal, Pierre; DAS, ALOKE (AIP Publishing, 2024-12)
    Herein, we have investigated the effect of microhydration on the secondary structure of a capped dipeptide Boc-DPro-Gly-NHBn-OMe (Boc = tert-butyloxycarbonyl, Bn = Benzyl), i.e., Pro–Gly (PG) with a single H2O molecule ...
