Abstract
The structure of Halobacterium halobium R(1)M(1) flagella is investiga ted by the methods of scanning microcalorimetry, circular dichroism, a nd electron microscopy. It is shown that melting curves of flagella in solutions with a different concentration of NaCl display only one pea k of heat capacity that corresponds to one cooperatively melting domai n. It is found that flagella do not dissociate after melting. The poss ible structural organization of archaebacterial flagella is discussed.
