Published: June 2012

β-Barrel proteins found in the outer membrane of Gram-negative bacteria serve a variety of cellular functions. Proper folding and assembly of these proteins are essential for the viability of bacteria and can also play an important role in virulence. The β-barrel assembly machinery (BAM) complex, which is responsible for the proper assembly of β-barrels into the outer membrane of Gram-negative bacteria, has been the focus of many recent studies. This review summarizes the significant progress that has been made toward understanding the structure and function of the bacterial BAM complex.

Infectious diseases caused by drug-resistant bacteria represent one of the most significant global public challenges of this century. There is an urgent need for the treatment of drug-resistant Gram-negative bacterial infections. A series of 3,4-dihydro-2H-[1,3]oxazino[5,6-h]quinoline derivatives were synthesized and evaluated for their antibacterial activity against Gram-negative bacteria including strains from ATCC and clinical isolates, initially revealing the structure-activity relationship.

The rapid spread of antibiotic-resistant strains of bacteria has created an urgent need for new alternative antibiotic agents. Membrane disrupting antimicrobial peptides (AMPs): short amino acid sequences with bactericidal and fungicidal activity that kill pathogens by permeabilizing their plasma membrane may offer a solution for this global health crisis. Magainin 2 is an AMP secreted by the African clawed frog (Xenopus laevis) that is described as a toroidal pore former membrane disrupting AMP.

Plastid-localized plastoglobules (PGs) are monolayer lipid droplets typically associated with the outer envelope of thylakoid membranes in chloroplasts. The size and number of PGs can vary significantly in response to different environmental stimuli. Since the early 21st century, a variety of proteins attached to the surface of PGs have been identified and experimentally characterized using advanced biotechnological techniques, revealing their biological functions.

The mitochondrial voltage-dependent anion channel (VDAC) is the major channel in the mitochondrial outer membrane for metabolites and ions. VDACs also regulate a variety of biological processes, which vary in the number of VDAC isoforms across different eukaryotes. However, little is known about VDAC-mediated biocontrol traits in biocontrol fungi.
