Analysis of autocatalytic reactions with michaelis-menten kinetics in an isothermal continuous stirred tank reactor
Kumar, Jyoti; Nath, Sunil (1997)A systematic analysis of the behavior of autocatalytic reactions obeying Michaelis-Menten kinetics and taking place in an isothermal continuous stirred tank reactor is presented. The mathematical model is solved for general ... -
Catalysis by ATP synthase: mechanistic, kinetic and theromodynamic characteristics
Jain, Siddhartha; Nath, Sunil (2001)Mechanistic,kinetic and thermodynamic aspects of ATP synthase have been determined and analyzed.Reversibility and inversibility of catalysis in ATP synthasis represent two contrasting modes of catalysis with important ... -
The detailed molecular mechanism of ATP synthesis in the F0 portion of ATP synthase reveals a non-chemiosmotic mode of energy coupling
Nath, Sunil; Jain, Siddhartha (2002)Based on our torsional mechanism of ion translocation, energy transduction and energy storage in ATP synthase [Curr. Sci. 75(1998) 716]; [Curr. Sci. 77 (1999) 167]; [Curr. Sci. 78 (2000) 23]; [Biochem. Biophys. Res. Commun. ... -
Kinetic model of ATP synthase: pH dependence of the rate of ATP synthesis
Jain, Siddhartha; Nath, Sunil (2000)Abstract Recently, a novel molecular mechanism of torque generation in the F0 portion of ATP synthase was proposed [Rohatgi, Saha and Nath (1998) Curr. Sci. 75, 716-718].In this mechanism, rotation of the c-subunit was ... -
Kinetic modeling of ATP synthesis by ATP synthase and Its mechanistic implications
Nath, Sunil; Jain, Siddhartha (2000)Based on the torsional mechanism of ATP synthesis by ATP synthase, a kinetic scheme has been developed in this work. The scheme considers adenine nucleotide transport, binding of substrates ADP and Pi, unbinding of product ... -
A new approach to evaluate kinetic parameters and mass transfer coefficient in continuous stirred tank reactors.Application to antibiotic separation
Nath, Sunil; Shukla, Vivek (1997)A method is proposed to evaluate kinetic parameters and mass transfer cofficients for adsorption processes carried out in continuous stirred tank reactors.This method,employing a biphasic model,does not linerize nonliner ... -

Role of water structure on phase separation in polyelectrolyte-polyethyleneglycol based aqueous two phase systems
Gupta, Vandana; Nath, Sunil; Chand, Subash (2002)Partitioning of proteins in aqueous two-phase system(ATPS)has emerged as one of the important downstream processing techneques in bioprocess technology.The phase separation behavior of polyelectrolyte-polythyleneglycol(PEG)based ... -
Surface tension of nonideal binary liquid mixtures as a function of composition
Nath, Sunil (1999)The composition dependence of the surface tension of highly nonideal organic–organic and aqueous–organic nonelectrolyte solutions is described, based on the assumption that the surface layer can be treated as a separate ... -
Thermal stability of alcohol dehydrogenase enzyme determined by activity assay and calorimetry
Nath, Sunil; Satpathy, Gyana R; Mantri, Rahul; Deep, Shashank; Ahluwalia, Jagdish C (1998)The thermostability of pure yeast alcohol dehydrogenase was investigated at various temperatures, in the presence and absence of sucrose, by both activity assay and differential scanning calorimetry. The thermal inactivation ... -
The torsional mechanism of energy transduction and ATP synthesis as a breakthrough in our understanding of the mechanistic, kinetic and thermodynamic details
Nath, Sunil (2004)Novel insights into mechanistic, kinetic and thermodynamic details of ATP synthesis by F1F0-ATP synthase in oxidative phosphorylation and photophosphorylation have been offered from the perspective of the torsional mechanism ...
