Family 1 includes Stearoyl-CoA desaturase-1 (SCD) (EC 1.14.19.1). [17] Family 2 is composed of: Bacterial fatty acid desaturases. Plant stearoyl-acyl-carrier-protein desaturase (EC 1.14.19.1), [18] an enzyme that catalyzes the introduction of a double bond at the delta-9 position of steraoyl-ACP to produce oleoyl-ACP. This enzyme is responsible ...
HdeA is one of the most abundant proteins found in the periplasmic space of E. coli, where it is one of a network of proteins that confer an acid resistance phenotype essential for the pathogenesis of enteric bacteria. [2] HdeA is thought to act as a chaperone, functioning to prevent the aggregation of periplasmic proteins denatured under ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Studies indicate that long-term diet is strongly associated with the gut microbiome composition—those who eat a higher proportion of protein and animal fats have predominantly Bacteroides bacteria, while for those who consume more carbohydrates or fiber the Prevotella species dominate. [10] One of the most important clinically is Bacteroides ...
Bacterial proteins are proteins from which any bacterium may be comprised in its natural state. Subcategories. This category has the following 4 subcategories, out of ...
There are many different families of chaperones; each family acts to aid protein folding in a different way. In bacteria like E. coli, many of these proteins are highly expressed under conditions of high stress, for example, when the bacterium is placed in high temperatures, thus heat shock protein chaperones are the most extensive.
An S-layer (surface layer) is a part of the cell envelope found in almost all archaea, as well as in many types of bacteria. [1] [2] The S-layers of both archaea and bacteria consists of a monomolecular layer composed of only one (or, in a few cases, two) identical proteins or glycoproteins. [3]
At high temperatures, these interactions cannot form, and a functional protein is denatured. [25] However, it relies on two factors; the type of protein used and the amount of heat applied. The amount of heat applied determines whether this change in protein is permanent or if it can be transformed back to its original form. [26]
