Project description:Differential gene expression analysis of C. glutamicum C1 in presence of 3 mM indole-alanine dipeptide compared to control conditions without indole-alanine dipeptide. C. glutamicum C1 cells were cultivated in CGXII minimal medium with 40 g per litre glucose in presence or absence of 3 mM indole-alanine dipeptide and harvested during exponential phase (o.d.600 6).

Project description:Corynebacterium glutamicum is able to grow with lactate as sole or combined carbon and energy source. Quinone-dependent L-lactate dehydrogenase LldD is known to be essential for utilization of L-lactate by C. glutamicum. D-lactate also serves as sole carbon source for C. glutamicum ATCC 13032. Here, the gene cg1027 was shown to encode the quinone-dependent D-lactate dehydrogenase (Dld) by enzymatic analysis of the protein purified from recombinant E. coli. The absorption spectrum of purified Dld indicated the presence of FAD as bound cofactor. Inactivation of dld resulted in the loss of the ability to grow with D-lactate, which could be restored by plasmid-borne expression of dld. Heterologous expression of dld from C. glutamicum ATCC 13032 in C. efficiens enabled this species to grow with D-lactate as sole carbon source. Homologs of dld of C. glutamicum ATCC 13032 are not encoded in the sequenced genomes of other corynebacteria and mycobacteria. However, the dld locus of C. glutamicum ATCC 13032 shares 2367 bp of 2372 bp identical nucleotides with the dld locus of Propionibacterium freudenreichii subsp. shermanii, a bacterium used in Swiss-type cheese making. Both loci are flanked by insertion sequences of the same family suggesting a possible event of horizontal gene transfer.

Project description:In a manner similar to ubiquitin, the prokaryotic ubiquitin-like protein (Pup) has been shown to target proteins for degradation via the proteasome in mycobacteria. However, not all actinobacteria possessing the Pup protein also harbor a proteasome, suggesting fates for pupylated proteins other than degradation via a proteasome or degradation at all. In the present study we set out to study pupylation in the proteasome-lacking non-pathogenic model microorganism and biotechnological workhorse Corynebacterium glutamicum. A defined pup deletion mutant of C. glutamicum ATCC 13032 grew as the control indicating that pupylation seems to be dispensable under the conditions tested. By expression of homologous Pup carrying a poly-histidine tag in C. glutamicum ATCC 13032 we purified the first pupylome of a microorganism lacking a proteasome. Multidimensional Protein Identification Technology (MudPIT) unraveled 54 proteins being pupylated in this organism. Similar to mycobacteria, the majority of pupylated proteins in C. glutamicum can be classified as enzymes of the metabolism or as involved in translation. These results help to elucidate the common target pathways of pupylation in bacteria. Sample 1: For growth in CGXII minimal media, a preculture 1 was grown in 5 ml BHI medium inoculated with a single colony from a fresh BHI agar plate and incubated at 170 rpm for 8 hours. Then 500 M-BM-5l of preculture 1 were used to inoculate preculture 2 in 100 ml shake flasks with 20 ml CGXII minimal medium containing 4 % (w/v) glucose and incubated over night (140 rpm , 30 M-BM-0C ). Subsequent main cultures (50 ml CGXII medium with 4 % glucose) were inoculated with cells from preculture 2 to an OD600 of about 0.4. For DNA microarray analysis, cells were harvested in the exponential growth phase at an OD600 of 4 to 5. After extraction of total RNA 25M-BM-5g of total RNA from C. glutamicum Delta-pup and C. glutamicum WT were compared in two-color microarray analysis. Overall three biological replicates were done. Sample 2-4: For growth in CGXII minimal media, a preculture 1 was grown in 5 ml BHI medium inoculated with a single colony from a fresh BHI agar plate and incubated at 170 rpm for 8 hours. Then 500 M-BM-5l of preculture 1 were used to inoculate preculture 2 in 100 ml shake flasks with 20 ml CGXII minimal medium containing 4 % (w/v) glucose and incubated over night (140 rpm , 30 M-BM-0C ). Subsequent main cultures (50 ml CGXII medium with 4 % glucose) were inoculated with cells from preculture 2 to an OD600 of about 0.4. For growth experiments in complex BHI medium, 20 ml brain heart infusion (BHI) medium (Difco Laboratories, Detroit, USA) were inoculated with a single colony from a fresh BHI agar plate and incubated at 140 rpm as overnight cultures. Subsequent main cultures (50 ml BHI medium) were inoculated with cells from overnight cultures to an optical density at 600 nm (OD600) of about 1. For DNA microarray analysis, cells were harvested in the exponential growth phase at an OD600 of 4 to 5. After extraction of total RNA 25M-BM-5g of total RNA from C. glutamicum Delta-pup and C. glutamicum WT were compared in two-color microarray analysis. Overall three biological replicates were done for each growth medium. Sample 5-6: For growth experiments in complex BHI medium, 20 ml brain heart infusion (BHI) medium (Difco Laboratories, Detroit, USA) were inoculated with a single colony from a fresh BHI agar plate and incubated at 140 rpm as overnight cultures.

| PRJNA669552 | ENA
Project description:We evaluated how HrrA binding (found by ChAP-Seq) impacts the expression of individual target genes, by analyzing the transcriptome of the C. glutamicum wild type strain (ATCC 13032) as well as a ∆hrrA mutant. RNA-Seq analysis was performed prior to the addition of heme (T0) and 0.5 and 4 h after the heme pulse (in medium containing no other iron source).

Project description:Corynebacterium glutamicum strain ATCC 21831 is a producer of L-arginine that was created by random mutagenesis. It is resistant to the arginine structural analogue canavanine. In order to identify potential bottlenecks in the biosynthetic pathway that leads to this industrially important amino acid, relative metabolite abundances of biosynthetic intermediates were determined in comparison to the type strain ATCC 13032. An extract of U13C-labeled biomass was used as internal standard, to correct for different ionization efficiencies. Metabolites were identified using the ALLocator web platform.

Project description:To understrand the altered global gene expression levels in C. glutamicum wild type in presence of furfural, transcriptome profiling was performed. Transcriptome profiles of the wild type grown in CgXII medium without furfural and with furfural stresses (each 6.5 mM, 13 mM, and 20 mM) were compared by using the samples taken at the OD600 of 6 (for the control and experiments). Each experiment was performed with a duplicate.
