Cholera01:25

Cholera

34
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...

Protein Folding Quality Check in the RER01:29

Protein Folding Quality Check in the RER

5.4K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

    Area of Science:

    • Biochemistry
    • Microbiology
    • Enzymology

    Context:

    • Chitinolytic enzymes play a vital role in microbial ecology and nutrient cycling.
    • Vibrio cholerae, the causative agent of cholera, possesses a chitinolytic system.
    • Understanding the specific enzymes involved is crucial for comprehending V. cholerae's survival and virulence.

    Purpose:

    • To investigate and characterize N-acetyl-β-D-glucosaminidase (chitobiase, EC 3.2.1.30) in various Vibrio cholerae strains.
    • To determine the enzyme's physical-chemical and biological properties.
    • To classify the enzyme within the glycosyl-hydrolase family.

    Summary:

    • N-acetyl-β-D-glucosaminidase was detected, purified, and characterized in V. cholerae O1 and non-O1 serogroups.
    • Comparative sequence analysis identified the enzyme as a member of glycosyl-hydrolases, family 20 (chitobiases).
    • The study provides the first detailed characterization of this enzyme in V. cholerae.

    Impact:

    • This research offers novel insights into the enzymatic machinery of V. cholerae.
    • The findings contribute to understanding the role of chitin utilization in the cholera pathogen's biology.
    • Characterization of this enzyme may have implications for future research on V. cholerae pathogenesis and control.
