Thio Effects and an Unconventional Metal Ion Rescue in the Genomic Hepatitis Delta Virus Ribozyme
Autor: Abir Ganguly, Sharon Hammes-Schiffer, Barbara L. Golden, Pallavi Thaplyal, Philip C. Bevilacqua
Publikováno v: Biochemistry. 52:6499-6514
Metal ion and nucleobase catalysis are important for ribozyme mechanism, but the extent to which they cooperate is unclear. A crystal structure of the hepatitis delta virus (HDV) ribozyme suggested that the pro-RP oxygen at the scissile phosphate dir

Synthesis of Core–Shell Nanostructures of Co3O4@SiO2 with Controlled Shell Thickness (5–20 nm) and Hollow Shells of Silica
Autor: Samuel E. Lofland, Sonalika Vaidya, Ashok K. Ganguli, Kandalam V. Ramanujachary, Pallavi Thaplyal
Publikováno v: Journal of Nanoscience and Nanotechnology. 11:3405-3413
Synthesis of uniform silica shell over Co 3 O 4 nanoparticles was carried out using the colloidal solutions of Tergitol and cyclohexane. The shell could be controlled to a thickness of up to 20 nm by varying different parameters such as the amount of

Controlling the Size, Morphology, and Aspect Ratio of Nanostructures Using Reverse Micelles: A Case Study of Copper Oxalate Monohydrate
Autor: Mohd. Qamar, Sonalika Vaidya, Jahangeer Ahmed, Ashok K. Ganguli, Rajeev Ranjan, Pallavi Thaplyal
Publikováno v: Langmuir. 25:6469-6475
This study focuses on understanding the growth and control of nanostructures using reverse micelles. It has been earlier realized that parameters like surfactant, cosurfactant, and aqueous content influence the size and shape of the nanostructures ob

Inverse thio effects in the hepatitis delta virus ribozyme reveal that the reaction pathway is controlled by metal ion charge density
Autor: Abir Ganguly, Sharon Hammes-Schiffer, Pallavi Thaplyal, Philip C. Bevilacqua
Publikováno v: Biochemistry
The hepatitis delta virus (HDV) ribozyme self-cleaves in the presence of a wide range of monovalent and divalent ions. Prior theoretical studies provided evidence that self-cleavage proceeds via a concerted or stepwise pathway, with the outcome dicta

Prospecting for Aptamers in the Human Genome
Autor: Peter C. Breen, Pallavi Thaplyal, Philip C. Bevilacqua
Publikováno v: Chemistry & Biology. 19:1218-1220
Aptamers are structured macromolecules in vitro evolved to bind molecular targets, whereas in nature they form the ligand-binding domains of riboswitches. Adenosine aptamers of a single structural family were isolated several times from random pools

Quantum mechanical/molecular mechanical free energy simulations of the self-cleavage reaction in the hepatitis delta virus ribozyme
Autor: Pallavi Thaplyal, Edina Rosta, Abir Ganguly, Sharon Hammes-Schiffer, Philip C. Bevilacqua
Publikováno v: Journal of the American Chemical Society
The hepatitis delta virus (HDV) ribozyme catalyzes a self-cleavage reaction using a combination of nucleobase and metal ion catalysis. Both divalent and monovalent ions can catalyze this reaction, although the rate is slower with monovalent ions alon

Experimental Approaches for Measuring pKa’s in RNA and DNA
Autor: Pallavi Thaplyal, Philip C. Bevilacqua
RNA and DNA carry out diverse functions in biology including catalysis, splicing, gene regulation, and storage of genetic information. Interest has grown in understanding how nucleic acids perform such sophisticated functions given their limited mole
