Multiply mutated Gaussia luciferases provide prolonged and intense bioluminescence.

25 Nov 2009 Gaussia luciferase (GLuc) from the copepod Gaussia princeps is both the smallest and brightest known luciferase. GLuc catalyzes the oxidation of coelenterazine to produce an intense blue light but with a very short emission half-life. We report ... Read more...

Periplasmic domains of Pseudomonas aeruginosa PilN and PilO form a stable heterodimeric complex.

18 Nov 2009 Type IV pili (T4P) are bacterial virulence factors responsible for attachment to surfaces and for twitching motility, a motion that involves a succession of pilus extension and retraction cycles. In the opportunistic pathogen Pseudomonas aeruginosa, ... Read more...

The second Cu(II)-binding site in a proton-rich environment interferes with the aggregation of amyloid-beta(1-40) into amyloid fibrils.

15 Nov 2009 The overall morphology and Cu(II) ion coordination for the aggregated amyloid-beta(1-40) [Abeta(1-40)] in N-ethylmorpholine (NEM) buffer are affected by Cu(II) ion concentration. This effect is investigated by transmission electron microscopy (TEM), ... Read more...
