Enzyme inhibitors block replication of SARS virus

...gs published today provide better insight into the mode of action of the enzyme, which may lead to development of a drug against SARS. The findings were made by using rapid drug discovery techniques developed in the Wong lab to screen large numbers of weak enzyme inhibitors, and then attaching additional ...

Even fish don't swim well when they're young!

...ae are pretty feeble when it comes to an efficient mode of swimming called 'burst-and-coast'. Dr Ulrike Mller from Wageningen University studies how fish swim: "Fish larvae are the most critical life history stage. In marine fish more than 99% of the mortality occurs in the larval stage so anything that m...

Salk scientist Ron Evans wins 2006 Gairdner Award for his discovery of hormone sensors

...rovided the much-needed code to hormones' puzzling mode of action and opened the door to future discoveries. Following his discovery, Evans, and others in his field began hunting for more hormone sensors by using the cortisol receptor gene as a blueprint. To date, researchers have turned up nearly 50 rela...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...plays a role in switching TFIIH from transcription mode to NER," Tainer says. "The structural biochemistry of XPB that we discovered shows an unexpected molecular mechanism by which XPB plays a key role in determining exactly how TFIIH functions, whether in transcription or repair mode."...

Brain communicates in analog and digital modes simultaneously

Quorum sensing in yeast

...ensity. While quorum sensing is a well-established mode of intercellular communication in bacteria, its role in fungal systems is still emerging. Dr. Chen and Fink found that S. cerevisiae use aromatic alcohols as signals to stimulate filamentous growth in response to nitrogen starvation. Interestingly, t...

Success comes at a cost, even for phages

...ion rate in a host, survival outside the host, and mode of transmission. Working with viruses that infect bacteria, called bacteriophages (or in this case, coliphages, which infect Escherichia coli), De Paepe and Taddei predicted that the phage, just like a full-fledged cellular organism, would display t...

Basically all cell reproduction shuts off," says Angela Luis, a doctoral candidate in ecology at Penn State's Center for Infectious Disease Dynamics. However, animals reg...

Researcher hits bulls-eye for antibiotic target

...ovides the signal for bacteria to enter starvation mode and limit reproduction. "With the ability to control the use of this signal, we can fool bacteria into thinking they are starving all the time, even when they are not; or we could never allow them to realize that they're starving, and that would ki...

Protein clue to tailor-made antibiotics

...leanthous has discovered a critical element in the mode of action of a class of colicins (so-called DNases) that kill cells by destroying their DNA. Though most proteins have a folded structure, DNase colicins are only partially so. The scientists have found that the unfolded part of DNase colicin struc...

These chemical signals also trigger the bacteria to produce slimy biofilms that cloak the bacteria and make the colony physically resistant to antibiotics. Attempts to block bacterial ...
