Comprehensive secondary-structure analysis of disulfide variants of lysozyme by synchrotron-radiation vacuum-ultraviolet circular dichroism.

29 Sep 2009 To elucidate the effects of specific disulfide bridges (Cys6-Cys127, Cys30-Cys115, Cys64-Cys80, and Cys76-Cys94) on the secondary structure of hen lysozyme, the vacuum-ultraviolet circular dichroism (VUVCD) spectra of 13 species of ... Read more...

Drosophila glycoprotein 93 Is an ortholog of mammalian heat shock protein gp96 (grp94, HSP90b1, HSPC4) and retains disulfide bond-independent chaperone function for TLRs and integrins.

26 Sep 2009 Mammalian heat shock protein gp96 is an obligate chaperone for multiple integrins and TLRs, the mechanism of which is largely unknown. We have identified gp93 in Drosophila having high sequence homology to gp96. However, no functions were previously ... Read more...

Disulfide bond formation in yeast NAD+-specific isocitrate dehydrogenase.

20 Sep 2009 The tricarboxylic acid cycle NAD+-specific isocitrate dehydrogenase (IDH) of Saccharomyces cerevisiae is an octameric enzyme composed of four heterodimers of regulatory IDH1 and catalytic IDH2 subunits. Recent structural analyses revealed the close ... Read more...
