| Abstract: | The uptake and the processing of molybdenum in nitrogen fixing bacteria was studied applying the TDPAC-technique with radioactive 99Mo. The observation of the nuclear quadrupole frequencies allowed a ‘finger-printing’ of the characteristic binding states in three bacteria species. The measurements have been carried out with intact cells and with the isolated proteins. In one bacterium a molybdenum storage protein was identified. This revised version was published online in August 2006 with corrections to the Cover Date. |
