The cis-(5R,6S)-thymine glycol lesion occupies the wobble position when mismatched with deoxyguanosine in DNA.

18 Oct 2009 Oxidative damage to 5-methylcytosine in DNA, followed by deamination, yields thymine glycol (Tg), 5,6-dihydroxy-5,6-dihydrothymine, mispaired with deoxyguanosine. The structure of the 5R Tg.G mismatch pair has been refined using a combination of ... Read more...

Deep-sea archaea fix and share nitrogen in methane-consuming microbial consortia.

14 Oct 2009 Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments. Using single-cell-resolution nanometer secondary ion mass spectrometry images ... Read more...

Using X-ray microscopy and Hg L3 XANES to study Hg binding in the rhizosphere of Spartina cordgrass.

29 Sep 2009 San Francisco Bay has been contaminated historically by mercury from mine tailings as well as contemporary industrial sources. Native Spartina foliosa and non-native S. alterniflora-hybrid cordgrasses are dominant florae within the SF Bay estuary ... Read more...
