Cell envelope of Nitrosocystis oceanus
Journal of Ultrastructure Research, 1970The cell envelope of Nitrosocystis oceanus, a marine nitrifying bacterium, has been shown to be composed of seven distinct layers including an outer fibrous slime layer, a hexagonal layer comprised of 50 A subunits, a double-tracked layer consisting of 40 A subunits, two globular layers which are separated by a mucopeptide layer, and a plasma membrane.

The cornified cell envelope (CE) is a highly insoluble structure on the inside of the plasma membrane of terminally differentiated keratinocytes. The cellular and molecular biology of the CE is outlined and new areas of research involving the CE are reviewed focussing on morphological and biochemical connections, the sequential gene expression during ...

The mycobacterial cell envelope — a moving target
Nature Reviews Microbiology, 2019Mycobacterium tuberculosis, the leading cause of death due to infection, has a dynamic and immunomodulatory cell envelope. The cell envelope structurally and functionally varies across the length of the cell and during the infection process. This variability allows the bacterium to manipulate the human immune system, tolerate antibiotic treatment and ...

The cell envelope of tubercle bacilli
Tuberculosis, 2015The envelope of tubercle bacilli and of other mycobacteria is important for the bacterial physiology since inhibition of the production of some of its constituents kills the cells. It consists of a plasma membrane, which is apparently homologous to plasma membranes of other bacteria, surrounded by a complex wall of carbohydrate and lipid, which is in ...

Mycobacterium tuberculosis Cell Envelope
1996The mycobacterial cell wall is a complex and intriguing mixture of components which sets Mycobacterium tuberculosis apart from all other known bacterial species (Goodfellow and Minnikin 1984). To understand the M. tuberculosis cell wall, one must first consider the biology of the tubercle bacillus.

The nuclear envelope of plant cells
Journal of Ultrastructure Research, 1960Potassium permanganate fixation and araldite embedding were used in a study of the nuclear envelope of three plant species. Arguments are advanced to support the idea that the “pores” of the nuclear envelope are simple openings devoid of a membrane or associated cylindrical extensions as postulated for some animal cells.

Natural products that target the cell envelope
Current Opinion in Microbiology, 2021The inexorable spread of resistance to clinically used drugs demands that we maintain a full pipeline of antibiotic candidates. As organisms have struggled to survive and compete over evolutionary history, they have developed the capacity to make a remarkably diverse array of natural products that target the cell envelope. A few have been developed for

Homeostasis of the Gram-negative cell envelope
Current Opinion in Microbiology, 2021The Gram-negative bacterial cell envelope is a complex structure and its homeostasis is essential for bacterial survival. Envelope stress responses (ESRs) are signal transduction pathways that monitor the fidelity of envelope assembly during normal growth and also detect and repair envelope damage caused by external assaults, including immune factors ...

Assembly of the epidermal cornified cell envelope
Journal of Cell Science, 2001The cornified cell envelope structure is formed beneath the plasma membrane in terminally differentiating stratified squamous epithelia. It provides a vital physical barrier to these tissues in mammals and consists of a 10 nm thick layer of highly crosslinked insoluble proteins.

Molecular Organization of Yeast Cell Envelope
Molecular Biology, 2019This review summarizes the main achievements of recent years in molecular organization research of yeast cell surface, i.e., the compartment that consists of the coordinately functioning plasma membrane, periplasmic space, and cell wall. There are data on vesicular transport to the external environment through the cell wall and the formation of ...
