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 کاملCloning, nucleotide sequence and characterization of the mannitol dehydrogenase gene from Rhodobacter sphaeroides.
Transposon mutagenesis and antibiotic enrichment were employed to isolate a mutant of Rhodobacter sphaeroides Si4 designated strain M22, that had lost the ability to grow on D-mannitol and to produce the enzyme mannitol dehydrogenase (MDH). DNA flanking the transposon in the mutant strain was used as a probe for the identification and cloning of the MDH gene (mtlK). A 5.5 kb EcoRI/BglII fragmen...
متن کاملIdentification of proteins involved in formaldehyde metabolism by Rhodobacter sphaeroides.
Formaldehyde is an intermediate formed during the metabolism of methanol or other methylated compounds. Many Gram-negative bacteria generate formaldehyde from methanol via a periplasmic pyrroloquinoline quinone (PQQ)-dependent dehydrogenase in which the alpha subunit of an alpha(2)beta(2) tetramer has catalytic activity. The genome of the facultative formaldehyde-oxidizing bacterium Rhodobacter...
متن کاملA minimal model for metabolism-dependent chemotaxis in Rhodobacter sphaeroides (†).
Chemotaxis is vital cellular movement in response to environmental chemicals. Unlike the canonical chemotactic pathway in Escherichia coli, Rhodobacter sphaeroides has both transmembrane and cytoplasmic sensory clusters, with the latter possibly interacting with essential components in the electron transport system. However, the effect of the cytoplasmic sensor and the mechanism of signal integ...
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...
