Regulation of Corynebacterium glutamicum Heat Shock Response by the Extracytoplasmic-Function Sigma Factor SigH and Transcriptional Regulators HspR and HrcA
Upregulation of 18 genes encoding transcriptional regulators by heat shock suggests a complex regulatory network of heat shock response in C. glutamicum. Expand
Identification of Lhcb gene family encoding the light-harvesting chlorophyll-a/b proteins of photosystem II in Chlamydomonas reinhardtii.
The Lhcb gene family in green plants encodes several light-harvesting Chl a/b-binding (LHC) proteins that collect and transfer light energy to the reaction centers of PSII, and these findings suggest that the ancestral LHC protein diverged into LHCII, CP29 and CP26 before, and that LHC II Diverged into multiple types after the phylogenetic separation of green algae and higher plants.

Group 2 Sigma Factor SigB of Corynebacterium glutamicum Positively Regulates Glucose Metabolism under Conditions of Oxygen Deprivation
SigB disruption reduced the transcript levels of genes involved in various cellular functions, including the glucose metabolism genes not only in the growth-arrested cells under conditions of oxygen deprivation but also in the cells during aerobic exponential growth, suggesting that SigB functions as another vegetative sigma factor.

Genome-Wide Identification of In Vivo Binding Sites of GlxR, a Cyclic AMP Receptor Protein-Type Regulator in Corynebacterium glutamicum
GlxR is physiologically functional at the relatively low cAMP levels in the cyaB mutant, allowing the cy aB mutant to grow much better than the glxR mutant, and is identified by chromatin immunoprecipitation in conjunction with microarray (ChIP-chip) analyses. Expand
Involvement of the LuxR-Type Transcriptional Regulator RamA in Regulation of Expression of the gapA Gene, Encoding Glyceraldehyde-3-Phosphate Dehydrogenase of Corynebacterium glutamicum
ABSTRACT SugR, RamA, GlxR, GntR1, and a MarR-type transcriptional regulator bind to the promoter region of the gapA gene encoding glyceraldehyde-3-phosphate dehydrogenase (GAPDH), essential forExpand
Light-Intensity-Dependent Expression of Lhc Gene Family Encoding Light-Harvesting Chlorophyll-a/b Proteins of Photosystem II in Chlamydomonas reinhardtii 1
The results indicate that two alternative processes are involved in the repression of Lhc genes under high-light conditions, one of which is independent of the photosynthetic reaction centers and electron transport events. Expand
DivS, a novel SOS‐inducible cell‐division suppressor in Corynebacterium glutamicum
Corynebacterium glutamicum R divS (cgR1759) was identified as an SOS‐inducible cell‐division suppressor in this study and showed no homology to that of YneA and Rv2719c. Expand
The ldhA Gene, Encoding Fermentative l-Lactate Dehydrogenase of Corynebacterium glutamicum, Is under the Control of Positive Feedback Regulation Mediated by LldR
It is shown that LldR is another protein that binds to the ldhA promoter region, thus regulating ldh a expression, and that in the absence of sugar, SugR-mediated repression of l dhA is alleviated, and ldh A expression is additionally enhanced by Lld R inactivation in response to L-lactate produced by LdhA.

The light-harvesting complex of photosystem I in Chlamydomonas reinhardtii: protein composition, gene structures and phylogenic implications.
A comprehensive characterization of all members of Lhc gene family in this alga revealed that LHCI proteins are more highly diverged than LHCII, suggesting functional differentiation of the protein components in LHCi. Expand
Regulation of expression of general components of the phosphoenolpyruvate: carbohydrate phosphotransferase system (PTS) by the global regulator SugR in Corynebacterium glutamicum
The results suggest that SugR represses ptsI and ptsH in the absence of PTS sugar and derepression is the mechanism for the induction of the general components of PTS. Expand
