Mutations in the Lipopolysaccharide Biosynthesis Pathway Interfere with Crescentin-Mediated Cell Curvature in Caulobacter crescentus [PDF]

open access: yes, 2010
Bacterial cell morphogenesis requires coordination among multiple cellular systems, including the bacterial cytoskeleton and the cell wall. In the vibrioid bacterium Caulobacter crescentus, the intermediate filament-like protein crescentin forms a cell

The subnuclear localization of tRNA ligase in yeast [PDF]

open access: yes, 1987
Yeast tRNA ligase is an enzyme required for tRNA splicing. A study by indirect immune fluorescence shows that this enzyme is localized in the cell nucleus. At higher resolution, studies using indirect immune electron microscopy show this nuclear location

Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly [PDF]

open access: yes, 2011
During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules.

Phosphoproteins and protein-kinase activity in isolated envelopes of pea (Pisum sativum L.) chloroplasts [PDF]

open access: yes, 1985
A protein kinase was found in envelope membranes of purified pea (Pisum sativum L.) chloroplasts. Separation of the two envelope membranes showed that most of the enzyme activity was localized in the outer envelope.

HIV-Envelope–Dependent Cell-Cell Fusion: Quantitative Studies [PDF]

open access: yesThe Scientific World JOURNAL, 2009
Interactionin vitrobetween cells infected with human immunodeficiency virus (HIV) and surrounding, uninfected, target cells often leads to cell fusion and the formation of multinucleated cells, called syncytia. The presence in HIV-infected individuals of virus strains able to induce syncytia in cultures of T cells is associated with disease progression

Mutations That Alter the Bacterial Cell Envelope Increase Lipid Production

open access: yesmBio, 2017
Lipids from microbes offer a promising source of renewable alternatives to petroleum-derived compounds. In particular, oleaginous microbes are of interest because they accumulate a large fraction of their biomass as lipids.

A Barrier to Entry: Examining the Bacterial Outer Membrane and Antibiotic Resistance

open access: yesApplied Sciences, 2023
Gram-negative bacteria can resist antibiotics by changing the permeability via their outer membrane. These bacteria have a complex cell envelope that incorporates an outer membrane separating the periplasm from the external environment.

In vitro and in vivo screening for novel essential cell-envelope proteins in Pseudomonas aeruginosa [PDF]

open access: yes, 2015
The Gram-negative bacterium Pseudomonas aeruginosa represents a prototype of multi-drug resistant opportunistic pathogens for which novel therapeutic options are urgently required.

The bacterial cell envelope [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2015
Antonie van Leeuwenhoek, a draper from Delft, using a tiny homemade microscope, first described microbes or ‘animalcules’ in a number of letters to the Royal Society. The letters specifically describe ‘animalcules’ in pepper water in 1676 (published 1677). The famous drawing of a swimming animalcule from a scraping of his teeth was in a letter of 1684 (

A Biological Signature for the Inhibition of Outer Membrane Lipoprotein Biogenesis

open access: yesmBio, 2022
The outer membrane (OM) of Gram-negative bacteria is an essential organelle that acts as a formidable barrier to antibiotics. Increasingly prevalent resistance to existing drugs has exacerbated the need for antibiotic discovery efforts targeting the OM ...
