Subunit organization and reversal-associated movements in the flagellar switch of Escherichia coli.
Bacterial flagella contain a rotor-mounted protein complex termed the switch complex that functions in flagellar assembly, rotation, and clockwise/counterclockwise direction control. In Escherichia coli and Salmonella, the switch complex contains the proteins FliG, FliM, and FliN and corresponds structurally with the C-ring in the flagellar basal body. Certain features of subunit organization i...
متن کاملCalcium influx regulates antibody-induced glycoprotein movements within the Chlamydomonas flagellar membrane.
The Chlamydomonas flagellar surface exhibits a number of dynamic membrane phenomena associated with whole-cell gliding locomotion and the early events in fertilization. Crosslinking of a specific population of flagellar surface-exposed glycoproteins with the lectin concanavalin A or an anti-carbohydrate mouse monoclonal antibody, designated FMG-1, results in a characteristic pattern of glycopro...
متن کاملFlagellar Agglutinins
1. Certain bacilli within one strain may lose their flagella and become non-motile. 2. The change in serological behavior associated with the change in motility indicates that the flagella possess an individual antigenic property. 3. Flagella can be separated from the bodies of the bacilli. 4. A strictly flagellar antiserum can be produced by the injection of a flagellar suspension. 5. This dir...
متن کاملOrigins of flagellar gene operons and secondary flagellar systems.
Forty-one flagellated species representing 11 bacterial phyla were used to investigate the origin of secondary flagellar systems and the structure and formation of flagellar gene operons over the course of bacterial evolution. Secondary (i.e., lateral) flagellar systems, which are harbored by five of the proteobacterial species considered, originated twice, once in the alphaproteobacterial line...
متن کاملThe spirochete FlaA periplasmic flagellar sheath protein impacts flagellar helicity.
Spirochete periplasmic flagella (PFs), including those from Brachyspira (Serpulina), Spirochaeta, Treponema, and Leptospira spp., have a unique structure. In most spirochete species, the periplasmic flagellar filaments consist of a core of at least three proteins (FlaB1, FlaB2, and FlaB3) and a sheath protein (FlaA). Each of these proteins is encoded by a separate gene. Using Brachyspira hyodys...
