Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella [PDF]

open access: yes, 1979
Asymmetrical bending waves can be obtained by reactivating demembranated sea urchin spermatozoa at high Ca2+ concentrations. Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the ...

Rab23 is a flagellar protein in Trypanosoma brucei

open access: yesBMC Research Notes, 2011
Background Rab small GTPases are important mediators of membrane transport, and orthologues frequently retain similar locations and functions, even between highly divergent taxa.

The Role of the Flagellar Protein FlgJ in the Virulence of Brucella abortus

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Brucella abortus is a facultative intracellular pathogen that causes a zoonosis called brucellosis. This disease leads to abortion and infertility in cattle, and diverse complications in humans. B. abortus is a successful intracellular bacterium that has

The Unicellular, Parasitic Fungi, Sanchytriomycota, Possess a DNA Sequence Possibly Encoding a Long Tubulin Polymerization Promoting Protein (TPPP) but Not a Fungal-Type One

open access: yesMicroorganisms, 2023
The unicellular, parasitic fungi of the phylum Sanchytriomycota (sanchytrids) were discovered a few years ago. These unusual chytrid-like fungi parasitize algae.

Computational Study of Micropropulsion Mechanism in Water Modeled on Flagellum with Projecting Mastigonemes

open access: yesJournal of Biomechanical Science and Engineering, 2009
The application of dynamics in organisms to the field of engineering is very instructive. From this point of view, we aimed at examining the micropropulsion mechanism modeled on aquatic microorganisms, and proposed a micropropulsion mechanism modeled on ...

A Proline-Rich Element in the Type III Secretion Protein FlhB Contributes to Flagellar Biogenesis in the Beta- and Gamma-Proteobacteria

open access: yesFrontiers in Microbiology, 2020
Flagella are bacterial organelles of locomotion. Their biogenesis is highly coordinated in time and space and relies on a specialized flagellar type III secretion system (fT3SS) required for the assembly of the extracellular hook, rod, and filament parts

Untargeted Microbial Exometabolomics and Metabolomics Analysis of Helicobacter pylori J99 and jhp0106 Mutant

open access: yesMetabolites, 2021
Untargeted metabolomic profiling provides the opportunity to comprehensively explore metabolites of interest. Herein, we investigated the metabolic pathways associated with Jhp0106, a glycosyltransferase enzyme in Helicobacter pylori.

APEX2 Proximity Proteomics Resolves Flagellum Subdomains and Identifies Flagellum Tip-Specific Proteins in Trypanosoma brucei [PDF]

open access: yesmSphere, 2020
Sleeping sickness is a neglected tropical disease caused by the protozoan parasite Trypanosoma brucei . The disease disrupts the sleep-wake cycle, leading to coma and death if left untreated. T. brucei motility, transmission, and virulence depend on its
