Complex and diverse signal transduction circuits are responsible for the efficient functioning of cellular network. Protein kinases and O-protein phosphatases are primarily responsible for propagating such stimuli within a eukaryotic cell. However, there is limited understanding of O-protein phosphatases in the prokaryotic genomes. The availability of(More)
Realization of conserved residues that represent a protein family is crucial for clearer understanding of biological function as well as for the better recognition of additional members in sequence databases. Functionally important residues are recognized well due to their high degree of conservation in closely related sequences and are annotated in(More)
MOTIVATION Biochemical pathways engineering is often used to synthesize or degrade target chemicals. In silico screening of the biochemical transformation space allows predicting feasible reactions, constituting these pathways. Current enabling tools are customized to predict reactions based on pre-defined biochemical transformations or reaction rule sets.(More)
The cardiac dynamics during meditation is explored quantitatively with two chaos-based non-linear techniques viz. multi-fractal detrended fluctuation analysis and visibility network analysis techniques. The data used are the instantaneous heart rate (in beats/minute) of subjects performing Kundalini Yoga and Chi meditation from PhysioNet. The results show(More)
UNLABELLED : Quantitative assessment of chemical reaction similarity aids database searches, classification of reactions and identification of candidate enzymes. Most methods evaluate reaction similarity based on chemical transformation patterns. We describe a tool, RxnSim, which computes reaction similarity based on the molecular signatures of(More)
Intricate molecular signalling within cellular environment is manifested through phosphorylation of proteins. Regulation of the phosphorylation state is executed through complex networking among kinases and their biochemical antagonists, the protein phosphatases. Protein dephosphorylation in eukaryotic systems is largely performed through four structurally(More)
Purified preparations of D-amino acid dehydrogenase [Olsiewski, P.J., Kaczorowski, G. J., & Walsh, C. T. (1980) J. Biol. Chem. 225, 4487] and D-lactate dehydrogenase [Kohn, L.D., & Kaback, H.R. (1973) J. Biol. Chem. 248, 7012] bind independently to right-side-out and inverted Escherichia coli vesicles and to phosphatidylcholine liposomes without detectable(More)
To enhance the activity of transketolase towards nonphosphorylated substrates and enlarge the scope of its substrates, notably to long polyol aldehyde acceptors (D-ribose or D-glucose), a rational design-supported evolution strategy was applied. By using docking experiments, an in silico library, and iterative mutagenesis, libraries of single- and(More)
Tyrosine phosphatases play an important role in cellular signalling and networking that is antagonistic to the kinases. Near completion of the human genome- sequencing project permits us to review the distribution of this family and study its involvement in different pathways. Ninety-six homologues of the classical and dual- specific tyrosine phosphatases(More)
Kinesin-2 is an anterograde motor involved in intraflagellar transport and certain other intracellular transport processes. It consists of two different motor subunits and an accessory protein KAP (kinesin accessory protein). The motor subunits were shown to bind each other through the coiled-coil stalk domains, while KAP was proposed to bind the tail(More)
