چکیده

The isolate major outer membrane protein from Rhodopseudomonas capsulata St. Louis (ATCC 23782) has a high porin activity in reconstituted phospholipid liposomes. The pore size of the homooligomeric porin with subunits of Mr 33,000 was determined to be about 0.8 nm in radius. Circular dichroism data revealed major portions of the beta structure. Heating of the oligomer resulted in monomer formation, loss of porin activity (60 to 70 degrees C), and change to alpha structure (100 degrees C).

Characterization of a soluble NADH-independent nitrate reductase from the photosynthetic bacterium Rhodopseudomonas capsulata.

The assimilatory nitrate reductase was purified 60-fold from a newly isolated, nitrate assmilating strain of the photosynthetic bacterium Rhodopseudomonas capsulata. The enzyme had a molecular weight of about 180 000 dalton and was typically prokaryotic in that it was not active with reduced pyridine nucleotides but rather with reduced flavins.

Genetic-physical mapping of a photosynthetic gene cluster from R. capsulata.

Transposon mutagenesis and complementation analysis of the photosynthesis genes in Rhodopseudomonas capsulata is presented utilizing Tn5.7 mutagenized R-primes. The R-prime pRPS404 contains many of the genes necessary for the differentiation of the photosynthetic apparatus. Utilizing homologous recombination, 30 independent copies of Tn5.7 were inserted into the R. capsulata chromosome with sub...

Anaerobic regulation of nitrogen-fixation genes in Rhodopseudomonas capsulata.

A Rhodopseudomonas capsulata nifH::lacZ gene fusion was used to isolate constitutive mutants of R. capsulata, unable to repress nif gene transcription anaerobically with every fixed-nitrogen source tested. When these nifc strains were grown aerobically, nif gene transcription was repressed. These results indicate that the regulation of nif gene transcription by fixed nitrogen is different from ...

Protein Sequence Homologies between Portions of the L and M Subunits of Reaction Centers of Rhodopseudomonas capsulata and the QB-Protein of Chloroplast Thylakoid Membranes: a Proposed Relation to Quinone-Binding Sites

Sequence homology has been found between the L and M subunits o f Rhodopseudomonas capsulata reaction centers and the Q B-protein from all species thus far sequenced. The hom ology between the L subunit and the Q B-protein is contained in the sequence PFH M L G -------F ---------A M H G -L V -S and is believed to have survived three billion years o f evolution. A model is presented which associ...

Nitrous oxide reduction by members of the family Rhodospirillaceae and the nitrous oxide reductase of Rhodopseudomonas capsulata.

After growth in the absence of nitrogenous oxides under anaerobic phototrophic conditions, several strains of Rhodopseudomonas capsulata were shown to possess a nitrous oxide reductase activity. The enzyme responsible for this activity had a periplasmic location and resembled a nitrous oxide reductase purified from Pseudomonas perfectomarinus. Electron flow to nitrous oxide reductase was couple...
