The uptake of 2-deoxy-D-glucose by Pseudomonas aeruginosa and its regulation

The Biochemical Journal

Abstract

The non-metabolizable glucose analogue 2-deoxy-d-glucose is taken up by Pseudomonas aeruginosa against a concentration gradient, in a predominantly unchanged form. d-Glucose competitively inhibits 2-deoxy-d-glucose uptake and also causes a rapid exit of intracellular 2-deoxy-d-glucose. Thus these two sugars share the same stereospecific carrier system, and glucose transport can be studied reliably with 2-deoxy-d-glucose. The transport system is inducible, and is strongly repressed by a number of organic acids such as acetate, citrate, succinate, fumarate and malate, even in the presence of adequate excess of the inducer (d-glucose). Repression by organic acids can be relieved by transferring cells to a glucose medium, but in the presence of chloramphenicol the cells fail to recover from repression, indicating that the formation of the transport system involves the synthesis of protein. The results demonstrate that the regulation of glucose metabolism effected by citric acid-cycle intermediates in P. aeruginosa is manifest at the level of the glucose-transport system.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
