Heterologous expression of correctly assembled methylamine dehydrogenase in Rhodobacter sphaeroides.
The biosynthesis of methylamine dehydrogenase (MADH) from Paracoccus denitrificans requires four genes in addition to those that encode the two structural protein subunits, mauB and mauA. The accessory gene products appear to be required for proper export of the protein to the periplasm, synthesis of the tryptophan tryptophylquinone (TTQ) prosthetic group, and formation of several structural di...
متن کاملOverexpression of pucC improves the heterologous protein expression level in a Rhodobacter sphaeroides expression system.
The Rhodobacter sphaeroides system has been used to express membrane proteins. However, its low yield has substantially limited its application. In order to promote the protein expression capability of this system, the pucC gene, which plays a crucial role in assembling the R. sphaeroides light-harvesting 2 complex (LH2), was overexpressed. To build a pucC overexpression strain, a pucC overexpr...
متن کاملOsmoregulation in Rhodobacter sphaeroides.
Betaine (N,N,N-trimethylglycine) functioned most effectively as an osmoprotectant in osmotically stressed Rhodobacter sphaeroides cells during aerobic growth in the dark and during anaerobic growth in the light. The presence of the amino acids L-glutamate, L-alanine, or L-proline in the growth medium did not result in a significant increase in the growth rate at increased osmotic strengths. The...
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 کاملTranslational control of puf operon expression in Rhodobacter sphaeroides 2.4.1.
The puf operon of Rhodobacter sphaeroides 2.4.1 encode the beta- and alpha-polypeptides of the B875 complex, the L and M polypeptides of the reaction centre and the pufX gene product. A previous report from the authors' laboratory indicated the potential existence of a 20-codon open reading frame (orfK, now designated pufK) located immediately upstream of the pufB structural gene. It is now dem...
