Exoproteome profiles of Clostridium cellulovorans grown on various carbon sources.
The cellulosome is a complex of cellulosomal proteins bound to scaffolding proteins. This complex is considered the most efficient system for cellulose degradation. Clostridium cellulovorans, which is known to produce cellulosomes, changes the composition of its cellulosomes depending on the growth substrates. However, studies have investigated only cellulosomal proteins; profile changes in non...
متن کاملAmmonia Assimilation by Thiocapsa roseopersicina Grown on Various Nitrogen and Carbon/Electron Sources
Thiocapsa roseopersicina, Phototrophic Bacteria, Nitrogen Sources, Ammonia Assimilation, Carbon Metabolism Batch cultures of the phototrophic bacterium, Thiocapsa roseopersicina, were grown anaero bically in the light either on sulfide with various ammonia concentrations, N 2 or amino acids as nitrogen sources, or on several simple organic substrates in the absence of reduced sulfur com pound...
متن کاملCellulose promotes extracellular assembly of Clostridium cellulovorans cellulosomes.
Cellulosome synthesis by Clostridium cellulovorans was investigated by growing the cells in media containing different carbon sources. Supernatant from cells grown with cellobiose contained no cellulosomes and only the free forms of cellulosomal major subunits CbpA, P100, and P70 and the minor subunits with enzymatic activity. Supernatant from cells grown on pebble-milled cellulose and Avicel c...
متن کاملTranscription of Clostridium cellulovorans cellulosomal cellulase and hemicellulase genes.
Transcription of the cellulosomal cellulase/hemicellulase genes of Clostridium cellulovorans has been investigated by Northern blot, reverse transcriptase PCR (RT-PCR), primer extension, and S1 nuclease analysis. Northern hybridizations revealed that the cellulosomal cbpA gene cluster is transcribed as polycistronic mRNAs of 8 and 12 kb. The 8-kb mRNA coded for cbpA and exgS, and the 12-kb mRNA...
متن کاملSynthesis of Clostridium cellulovorans minicellulosomes by intercellular complementation.
The ability of two strains of bacteria to cooperate in the synthesis of an enzyme complex (a minicellulosome) was examined. Three strains of Bacillus subtilis were constructed to express Clostridium cellulovorans genes engB, xynB, and minicbpA. MiniCbpA, EngB, and XynB were synthesized and secreted into the medium by B. subtilis. When the strains with the minicbpA and engB genes or with xynB we...
