Genetic analysis of a bacterial genetic exchange element: the gene transfer agent of Rhodobacter capsulatus.
An unusual system of genetic exchange exists in the purple nonsulfur bacterium Rhodobacter capsulatus. DNA transmission is mediated by a small bacteriophage-like particle called the gene transfer agent (GTA) that transfers random 4.5-kb segments of the producing cell's genome to recipient cells, where allelic replacement occurs. This paper presents the results of gene cloning, analysis, and mut...
متن کاملComplexes of Rhodobacter sphaeroides and Rhodobacter capsulatus
Photosynthetic bacteria offer excellent experimental opportunities to explore both the structure and function of the ubiquinol-cytochrome c oxidoreductase (bcl complex). In both Rhodobacter sphaeroides and Rhodobaeter capsulatus, the bCl complex functions in both the aerobic respiratory chain and as an essential component of the photosynthetic electron transport chain. Because the bc~ complex i...
متن کاملRegulation of the glnBA operon of Rhodobacter capsulatus.
In a recent report identifying the promoters of the Rhodobacter capsulatus glnBA operon, it was suggested that an internal promoter upstream of the glnA gene probably resulted in different levels of glnBA and glnA transcripts (D. Foster-Hartnett and R. G. Kranz, J. Bacteriol. 176:5171-5176, 1994). Therefore, to investigate the regulation, we constructed and examined the expression of a number o...
متن کاملCloning, characterization, and regulation of nifF from Rhodobacter capsulatus.
The Rhodobacter capsulatus nifF gene and upstream sequence were cloned by using a probe based on the N-terminal sequence of NifF. nifF was found to not be contained in the previously described nif regions I, II, and III. Comparison of the deduced amino acid sequence showed that it is highly similar to NifF from Azotobacter vinelandii and NifF from Klebsiella pneumoniae. Analysis of translationa...
متن کاملPhysiological control and regulation of the Rhodobacter capsulatus cbb operons.
The genes encoding enzymes of the Calvin-Benson-Bassham (CBB) reductive pentose phosphate pathway in Rhodobacter capsulatus are organized in at least two operons, each preceded by a separate cbbR gene, encoding potential LysR-type transcriptional activators. As a prelude to studies of cbb gene regulation in R. capsulatus, the nucleotide sequence of a 4,537-bp region, which included cbbRII, was ...
