Researchers develop filter coating that traps bacteria and viruses

Article Abstract:

Prof Ben Koopman and his colleagues developed a coating that enables a pool's filter to trap the Escherichia coli bacterium, thus preventing the spread of diseases. They claimed that the coating could trap bacteria, viruses and particles as small as 500 angstroms because of its ability to give pool filters a positive electrical charge. The coating can also be utilized in silicon chip manufacturing and military applications.

Enzyme's structure yields blueprint for antibiotic resistance

Article Abstract:

Researchers from the Howard Hughes Medical Institute at the Rockefeller University in New York have characterized the molecular structure of aminoglycoside 3-N-acetyltransferase, an enzyme from the bacterium Serratia marcescens. The three dimensional structured depicted how the enzyme positions the donor and recipient during the transfer of an acetyl group from a dnor molecule to a recipient molecule.

NASA research helps map protein structures

Article Abstract:

NASA is conducting space and ground-based studies designed to advance scientists' understanding of protein structures and functions, including the development of novel disease-fighting drugs. Some of these advances include the development of a treatment for respiratory syncytial virus, characterization of insulin proteins and the resolution of the structure of the HIV protease/inhibitor complex.
