Porin from Rhodopseudomonas sphaeroides [PDF]
Journal of Bacteriology, 1984 A protein homooligomer was purified from both the cell envelope fractions and the saline extracts of Rhodopseudomonas sphaeroides cells. This oligomer exhibited strong porin activity when reconstituted into proteoliposomes with egg phosphatidylcholine. In the saline extracts of both chemotrophically and phototrophically grown cells, the porin oligomer ...

Angewandte Chemie, EarlyView.KO‐NH2 is a synthetic metallophore that preferentially binds Ga3+ over Fe3+ and is recognized by bacterial transporters. Photocrosslinking identifies CirA and Fiu as key uptake proteins in E. coli. KO‐NH2 enables targeted imaging and treatment of E. coli soft tissue infections.

Asymmetric conductivity of engineered porins [PDF]
Protein Engineering, Design and Selection, 2002 Positively charged peptide segments of 16 and 18 residues were inserted at a periplasmic turn of the porin from Rhodobacter blasticus in order to form an electric field-dependent plug. The X-ray diffraction analysis of a mutant confirmed that the structure of the porin had remained intact and that the insert was mobile.

Fluoroquinolone-Transition Metal Complexes: A Strategy to Overcome Bacterial Resistance
Microorganisms, 2021 Fluoroquinolones (FQs) are antibiotics widely used in the clinical practice due to their large spectrum of action against Gram-negative and some Gram-positive bacteria.

Socialization of Providencia stuartii Enables Resistance to Environmental Insults
Microorganisms, 2022 Providencia stuartii is a highly social pathogen responsible for nosocomial chronic urinary tract infections. The bacterium indeed forms floating communities of cells (FCC) besides and prior-to canonical surface-attached biofilms (SAB).

Structural and Immunological Characterization of Novel Recombinant MOMP-Based Chlamydial Antigens
Vaccines, 2017 Chlamydia is the most common cause of bacterial sexually transmitted infections worldwide. While infections resolve with antibiotic treatment, this is often neglected in women due to frequent asymptomatic infections, leading to disease progression and ...

Antibiotics, 2023 The treatment of infections by Gram-negative bacteria remains a difficult clinical challenge. In the light of the dearth of discovery of novel antibiotics, one strategy that is being explored is the use of adjuvants to enhance antibacterial activities of

Advanced Science, EarlyView.Chronic microinflammation in high myopia suppresses MANF in lens epithelial cells. MANF normally resides within MAMs and promotes ubiquitin‐mediated degradation of the ER Ca2+ pump SERCA2. MANF loss causes pathological SERCA2 accumulation, MAM hyperassembly, and disrupted ER‐to‐mitochondria Ca2+ transfer, leading to mitochondrial failure, oxidative ...
