Kerby R, Roberts G
J Bacteriol
. 2012 Aug;
194(21):5803-16.
PMID: 22923594
The single-component RcoM transcription factor couples an N-terminally bound heme cofactor with a C-terminal "LytTR" DNA-binding domain. Here the RcoM(Bx)-1 protein from Burkholderia xenovorans LB400 was heterologously expressed and then...

. 2012 Aug;
17(7):1071-82.
PMID: 22855237
The CO-responsive transcriptional regulator RcoM from Burkholderia xenovorans (BxRcoM) was recently identified as a Cys(thiolate)-ligated heme protein that undergoes a redox-mediated ligand switch; however, the Cys bound to the Fe(III)...

Stand Genomic Sci
. 2011 Sep;
4(3):293-302.
PMID: 21886856
Rhodospirillum rubrum (Esmarch 1887) Molisch 1907 is the type species of the genus Rhodospirillum, which is the type genus of the family Rhodospirillaceae in the class Alphaproteobacteria. The species is...

193(18):4859-68.
PMID: 21764924
Vfr, a transcription factor homologous to the Escherichia coli cyclic AMP (cAMP) receptor protein (CRP), regulates many aspects of virulence in Pseudomonas aeruginosa. Vfr, like CRP, binds to cAMP and...

. 2011 May;
193(13):3293-303.
PMID: 21531802
Ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) catalyzes the first step of CO(2) fixation in the Calvin-Benson-Bassham (CBB) cycle. Besides its function in fixing CO(2) to support photoautotrophic growth, the CBB cycle is also...

J Bacteriol
. 2010 Dec;
193(3):774-7.
PMID: 21115659
Low levels of carbon monoxide inhibit the N(2)-dependent growth of Rhodospirillum rubrum unless the ∼100-residue CowN protein is expressed. Expression requires the CO-responsive regulator RcoM and is maximal in cells...

Int J Hydrogen Energy
. 2010 Jul;
35(14):7377-7385.
PMID: 20652089
Nitrogenase not only reduces atmospheric nitrogen to ammonia, but also reduces protons to hydrogen (H(2)). The nitrogenase system is the primary means of H(2) production under photosynthetic and nitrogen-limiting conditions...

. 2010 Apr;
192(11):2711-21.
PMID: 20363937
GlnD is a bifunctional uridylyltransferase/uridylyl-removing enzyme (UTase/UR) and is believed to be the primary sensor of nitrogen status in the cell by sensing the level of glutamine in enteric bacteria....

Cyclic di-GMP allosterically inhibits the CRP-like protein (Clp) of Xanthomonas axonopodis pv. citri
Leduc J, Roberts G
J Bacteriol
. 2009 Jul;
191(22):7121-2.
PMID: 19633082
The protein Clp from Xanthomonas axonopodis pv. citri regulates pathogenesis and is a member of the CRP (cyclic AMP receptor protein) superfamily. We show that unlike the DNA-binding activity of...

J Bacteriol
. 2009 Jun;
191(17):5526-37.
PMID: 19542280
Nitrogenase activity in Rhodospirillum rubrum and in some other photosynthetic bacteria is regulated in part by the availability of light. This regulation is through a posttranslational modification system that is...
