Structure and Substrate Recognition of the Escherichia coli Transport Protein NupG from the Nucleoside: H+ Symporter (NHS) Family

The nucleoside transporter NupG is one of the two principal transport proteins in the inner membrane of Escherichia coli that enable the organism to scavenge nucleosides from its external environment. NupG functions in a symport manner driven by the proton motive force and is a member of the Nucleoside:H+ Symporter (NHS) subfamily of the Major Facilitator Superfamily (MFS) of transporters. NupG has broad substrate specificity, transporting all naturally occurring purine and pyrimidine nucleosides. In studies over many years the nupG gene has been cloned and amplified, and the NupG protein has been purified, subjected to biochemical, biophysical and computational analysis, and its X-ray structure determined in the apo state at 3.0 Å resolution. The NupG structure had a typical MFS fold with twelve transmembrane spanning α-helices and distinct N- and C-terminal domains linked by a flexible loop. Preliminary site-directed mutagenesis and molecular docking studies on NupG identified nine putative nucleoside binding pocket residues (R136, T140, F143, Q225, N228, Q261, E264, Y318, F322) and a mutant (D323A) with 20-fold enhanced uridine binding activity. Further biochemical and structural investigations are necessary to better understand the substrate recognition and molecular mechanism of E. coli NHS family proteins (NupG, XapB, YegT).

Recent Advances in the Treatment of Irritable Bowel Syndrome: Addressing Diarrhea, Constipation, and Abdominal Pain

Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits. This paper aim was to provide an overview of recent advancements in the treatment of IBS, focusing on the management of its main symptoms: diarrhea, constipation, and abdominal pain.

For individuals with IBS-D, various therapeutic options are available, including rifaximin, peripheral opioid agonists, mixed opioid agonists/antagonists, bile acid sequestrants, and serotonin 5-HT3 receptor antagonists. Rifaximin, a nonabsorbable antibiotic, has demonstrated significant effectiveness in reducing IBS symptoms, such as bloating and loose stools, with good tolerability and safety. Also the repeated use of rifaximin for managing recurrent IBS symptoms. In IBS-C patients, bulking agents, osmotic laxatives, and prokinetic agents like lubiprostone have shown efficacy in improving constipation and overall symptoms. Linaclotide, a drug that increases intestinal chloride secretion, has demonstrated significant improvement in bowel movements and abdominal pain in IBS-C patients. However, it may cause diarrhea in some individuals. IBS-M, characterized by alternating constipation and diarrhea, poses a challenge in terms of specific drug treatments. A comprehensive assessment of potential underlying causes and careful history taking is crucial for effective management. Abdominal pain is a common symptom in IBS, regardless of subtype. Antispasmodic drugs, peppermint oil, and trimebutine have shown effectiveness in reducing pain and improving symptoms. Antidepressants, such as tricyclic antidepressants and selective serotonin reuptake inhibitors, may offer relief by modulating pain pathways and influencing gastrointestinal motility. Benzodiazepines, particularly dextofisopam, have shown potential in improving stool consistency but require further evaluation.

In conclusion, recent advancements in the treatment of IBS have provided a range of therapeutic options targeting its main symptoms. However, further research is needed to develop tailored treatments for specific IBS subtypes and to explore the efficacy of potential alternatives, including benzodiazepines. Improved management of IBS symptoms can significantly enhance the quality of life for affected individuals.
