Ein universeller, kontinuierlicher Assay für SAM‐abhängige Methyltransferasen
Die Identifizierung neuer oder verbesserter Methyltransferasen (MTs) kann eine Schlüsselrolle bei der Entwicklung neuer pharmazeutischer Wirkstoffe (APIs) spielen, da sie die chemo‐ und regioselektive Methylierung von O‐, N‐, S‐ und C‐Atomen katalysieren. Um geeignete SAM‐abhängige MTs zu identifizieren, wurde der erste universelle, fluoreszenzbasierte

A Universal, Continuous Assay for SAM‐dependent Methyltransferases
Identification of novel or improved methyltransferases (MTs) may play a key role in the development of new active pharmaceutical ingredients (APIs), as they catalyze the chemo‐ and regioselective methylation of O‐, N‐, S‐ and C‐atoms. To identify suitable SAM‐dependent MTs, the first universal, fluorescence‐based high‐throughput MT assay compatible ...

DNA Sequence and Mutational Analysis of Rhizobitoxine Biosynthesis Genes in Bradyrhizobium elkanii [PDF]
ABSTRACT We cloned and sequenced a cluster of genes involved in the biosynthesis of rhizobitoxine, a nodulation enhancer produced by Bradyrhizobium elkanii . The nucleotide sequence of the cloned 28.4-kb DNA region encompassing rtxA showed that several open reading frames (ORFs ...

Abstract The use of the phenoxy herbicide 2,4‐dichlorophenoxyacetic acid (2,4‐D) has been steadily increasing in recent years due to its selectivity against broad‐leafed weeds and use on genetically modified crops resistant to 2,4‐D. This increases the likelihood of 2,4‐D persisting in agriculturally impacted soils, sediments, and aquatic systems ...

Draft Genome Sequence of the Nitrogen-Fixing Symbiotic Bacterium Bradyrhizobium elkanii 587 [PDF]
ABSTRACT The draft sequence of the genome of Bradyrhizobium elkanii 587 is presented. This was obtained using Illumina Next-Gen DNA sequencing combined with Sanger sequencing. Genes for the pathways involved in biological nitrogen fixation (the nif gene cluster), nod

A Selective Medium for the Isolation and Quantification of Bradyrhizobium japonicum and Bradyrhizobium elkanii Strains from Soils and Inoculants [PDF]
The ecological examination of members of the family Rhizobiaceae has been hampered by the lack of a selective medium for isolation of root nodule bacteria from soil. A novel non-antibiotic-containing medium has been developed which allows selective isolation of Bradyrhizobium japonicum and

Quantitative and time-course evaluation of nodulation competitiveness of rhizobitoxine-producing Bradyrhizobium elkanii [PDF]
Abstract Regression analysis of results from a mathematical competition model showed that rhizobitoxine production by Bradyrhizobium elkanii USDA94 gave this strain a nodulation competitiveness about 10 times greater than that of a non-rhizobitoxine-producing mutant strain on Macroptilium atropurpureum (Siratro).
