   Sammanfattning : A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. LÄS MER

   Sammanfattning : Ribonculeotide reductase (RNR) plays a key role in catalysing a reaction that provides all living organisms with building blocks for DNA. The RNR enzyme catalyses the conversion of ribonucleotides to their corresponding deoxyribonucleotides, by using free radical chemistry. LÄS MER
