#weekendusers Resolving the mystery of the Earth’s missing gas

04-11-2016

The atmospheres of the Earth and Mars are depleted of the noble gas Xenon, whilst meteorites similar to the rocky material that formed the Earth have it in abundance. All the other so-called noble gases appear in the Earth, Mars and meteorites. So what happened to Xenon...

Crystal structure of PolD provides a novel paradigm for the classification of DNA polymerases

01-11-2016

Polymerase D, PolD, an archaeal replicative DNA polymerase, is the only class of DNA-polymerases whose structure remains unknown and for which the catalytic domain has no assigned fold. The structure of both catalytic subunits of PolD was determined using data collected...
