Structural Studies on Phycobiliproteins

Studies of the amino acid sequence of the p subunit of Synechococcus sp. 6301 C-phycocyanin are presented. Sequences were determined of the NH,-terminal cyanogen bromide peptide (residues 1 to 78), and of the cyanogen bromide peptide (residues 86 to 133), containing the sole free cysteinyl residue of the protein. The overlap between these two peptides and the two other cyanogen bromide peptides...

Structural studies on cellulases.

Recent advances in chemical methodologies, together with the technique of X-ray structure analysis, are providing profound structural and mechanistic insights into cellulase action. At the structural level, detailed analyses of nearly all the enzyme families involved in cellulose breakdown are not known. Oligosaccharide complexes for all these enzymes have not yet been described, but utilizatio...

Structural studies on desmosomes.

Desmosomes are cadherin-based intercellular junctions that primarily provide mechanical stability to tissues such as epithelia and cardiac muscle. Desmosomal cadherins, which are Ca(2+)-dependent adhesion molecules, are of central importance in mediating direct intercellular interaction. The close association of these proteins, with intracellular components of desmosomes ultimately linked to th...

Structural studies on the interaction of nano-SiO2 with lysozyme

The interaction between nano-SiO2 and lysozyme was investigated by the method of UV-Visible  detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-SiO2 over the temperature range (293-373) K in different buffers and pH values, using temperature scanning spectroscopy. The presence of nano-SiO2 caused th...
