Structural basis of heteromeric smad protein assembly in TGF-beta signaling.
The formation of protein complexes between phosphorylated R-Smads and Smad4 is a central event in the TGF-beta signaling pathway. We have determined the crystal structure of two R-Smad/Smad4… Expand

The mode of binding of aromatic ligands in the substrate binding site on the distal heme side in heme peroxidases is well understood. However, the mode of diffusion through the extended hydrophobic… Expand
Stabilization of yeast hexokinase A by polyol osmolytes: correlation with the physicochemical properties of aqueous solutions.
Osmolytes of the polyol series are known to accumulate in biological systems under stress and stabilize the structures of a wide variety of proteins. While increased surface tension of aqueous… Expand
Microwave synthesized chitosan-graft-poly(methylmethacrylate): An efficient Zn2+ ion binder
Abstract Microwave promoted grafting of methylmethacrylate on to the chitosan has been optimized. Chitosan- graft -poly(methylmethacrylate) (Ch- g -PMMA) could be synthesized with 160% grafting using… Expand
Poly(acrylonitrile) grafted Ipomoea seed-gums: a renewable reservoir to industrial gums.
Plants of Ipomoea genus are widely distributed in India as wild vegetation and are reported source for the seed gums. Seed gums from Ipomoea dasysperma, Ipomoea hederacea, and Ipomoea palmata plants… Expand

Amphiphilic guar gum grafted with poly(ε-caprolactone) (GG-g-PCL) was fabricated as a drug-delivery carrier using microwave irradiation. The structure of the GG-g-PCL co-polymer was characterized by… Expand
Synthesis of Chemical Responsive Chitosan–Grafted-Polyaniline Bio-Composite
A polysaccharide based bioplolymer, chitosan was grafted with polyaniline through a simple room temperature oxidative-radical copolymerization method employing CuSO4 as a polymerizing agent. The… Expand
Microwave accelerated synthesis and characterization of poly(acrylamide)
Poly(acrylamide) (PAM) was efficiently synthesized under microwave (MW) irradiation using catalytic amount of potassium persulfate. The synthesis does not require any inert atmosphere and could be… Expand
