Characterization of covalent adducts of nucleosides and DNA formed by reaction with levuglandin.

15 Nov 2009 Enhanced expression of cyclooxygenase-2 (COX-2) is associated with development of several cancers. The product of COX-2, prostaglandin H(2) (PGH(2)), can undergo spontaneous rearrangement and nonenzymatic ring cleavage to form the highly reactive ... Read more...

Sortase activity is controlled by a flexible lid in the pilus biogenesis mechanism of gram-positive pathogens.

8 Nov 2009 Pili are surface-linked virulence factors that play key roles in infection establishment in a variety of pathogenic species. In Gram-positive pathogens, pilus formation requires the action of sortases, dedicated transpeptidases that covalently ... Read more...

Copper binding to beta-2-microglobulin and its pre-amyloid oligomers.

18 Oct 2009 Beta-2-microglobulin (beta2m) deposits as amyloid fibrils in the musculoskeletal system of patients undergoing long-term dialysis treatment as a result of kidney failure. Previous work has shown that Cu(II) binding causes beta2m to organize into ... Read more...
