[PDF] CooA, a CO-sensing transcription factor from ...

Biological sensing of small molecules such as NO, O2, and CO is an important area of research; however, little is know about how CO is sensed biologically. The photosynthetic bacterium Rhodospirillum rubrum responds to CO by activating transcription of two operons that encode a CO-oxidizing system. A protein, CooA, has been identified as necessary for this response.

1999-04-16· CooA is a CO-sensing transcription activator fromRhodospirillum rubrum, and it activates the expression of the cooFSCTJ and cooMKLXUH operons in response to CO (1, 2, 3).These two adjacent operons encode proteins that oxidize CO to CO 2 with concomitant reduction of H + to H 2 and allow growth of this organism on CO as a sole energy source (4, 5, 6). cooA lies immediately 3′ of …

Transcription Activation by CooA, the CO-sensing Factor ...

CooA, a member of the cAMP receptor protein (CRP) family, is a CO-sensing transcription activator fromRhodospirillum rubrum that binds specific DNA sequences in response to CO. The location of the CooA-binding sites relative to the start sites of transcription suggested that the CooA-dependent promoters are analogous to class II CRP-dependent promoters. In this study, we developed anin vivo ...

Identification of Two Important Heme Site Residues ...

1999-02-09· The CO-sensing mechanism of the transcription factor CooA from Rhodospirillum rubrum was studied through a systematic mutational analysis of potential heme ligands. Previous electron paramagnetic resonance (EPR) spectroscopic studies on wild-type CooA suggested that oxidized (FeIII) CooA contains a low-spin heme with a thiolate ligand, presumably a cysteine, bound to its heme iron.

Capacitive sensing - Wikipedia

In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, pressure, position and displacement, force, humidity, fluid level, and ...

Guanidine hydrochloride-induced unfolding of the three ...

2009-07-01· CooA is a heme-dependent CO-sensing transcription factor that has three observable heme coordination states. There is some evidence that each CooA heme state has a distinct protein conformation; the goal of this study was to characterize these conformations by measuring their structural stabilities through guanidine hydrochloride (GuHCl) denaturation.

Although NO-sensing (soluble guanylyl cyclase) (1, 2) and O 2-sensing (FixL) (3, 4) proteins have been studied, little data on CO-sensing proteins CO binding and CO inhibition of metalloproteins such as cytochromes has been extensively researched, but little is known of …

2021-01-15· These studies show the value of CO 2 sensing for assessing ventilation as a factor in transmission risk; however, establishing a CO 2 threshold that can reliably signal elevated COVID-19 risk is more complex. As described by Peng and Jimenez, occupants’ activity levels and other factors, like the use of masks, make selecting a single threshold problematic; rather, the authors suggest an ...
