Biogeography of the purple nonsulfur bacterium Rhodopseudomonas palustris

Article Abstract:

The authors have investigated spatial distributions of Rhodopseudomonas palustris's genetically distinct ecotypes on a local scale. The isolation of the bacteria's clones from the sampling locations has been carried out, and the clone genotypes have been determined via repetitive element PCR genomic DNA fingerprinting using BOX A1R primer.

Corynebacterium ammoniagenes class Ib ribonucleotide reductase: transcriptional regulation of an atypical genomic organization in the nrd cluster

Article Abstract:

Research has been conducted on ribonucleotide reductases which catalyse the synthesis of deoxyribonucleotides required for RNA repair and replication. The authors describe their study of these reductases carried out in accordance to their metal cofactors and organic radicals.
