Cell wall the cell membrane is the bacterial cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria, although L-form bacteria can be produced in the laboratory that lack a cell wall. The antibiotic penicillin is able to
Glucose 6-phosphatase a highly conserved residue that completely destroyed G6PT activity. These mutations lead to the prevalence of GSD-1 by preventing the transport of glucose-6-phosphate (G6P) into the luminal portion of the ER and also inhibiting the conversion of G6P into glucose to be used by the cell. The third type of glucose-6-phosphatase deficiency, glucose-6-phosphatase-β deficiency, is characterized by a congenital neutropenia syndrome in which neutrophils exhibit enhanced endoplasmic reticulum (ER) stress, increased apoptosis, impaired energy homeostasis, and impaired functionality. It can also lead to cardiac and urogenital malformations. This third class of deficiency is also affected by a G6PT deficiency as
