چکیده
We have determined the nucleotide sequence of a flagellin gene locus from the haloalkaliphilic archaeon Natrialba magadii, identified the gene products among proteins forming flagella, and demonstrated cotranscription of the genes. Based on the sequence analysis we suggest that different regions of the genes might have distinct evolutionary histories including possible genetic exchange with bacterial flagellin genes.

The archaeal flagellum: a different kind of prokaryotic motility structure.
The archaeal flagellum is a unique motility apparatus distinct in composition and likely in assembly from the bacterial flagellum. Gene families comprised of multiple flagellin genes co-transcribed with a number of conserved, archaeal-specific accessory genes have been identified in several archaea. However, no homologues of any bacterial genes involved in flagella structure have yet been ident...
متن کاملCoexistence of bacterial leucyl-tRNA synthetases with archaeal tRNA binding domains that distinguish tRNALeu in the archaeal mode
Leucyl-tRNA (transfer RNA) synthetase (LeuRS) is a multi-domain enzyme, which is divided into bacterial and archaeal/eukaryotic types. In general, one specific LeuRS, the domains of which are of the same type, exists in a single cell compartment. However, some species, such as the haloalkaliphile Natrialba magadii, encode two cytoplasmic LeuRSs, NmLeuRS1 and NmLeuRS2, which are the first exampl...
متن کاملN-glycosylation of Haloferax volcanii flagellins requires known Agl proteins and is essential for biosynthesis of stable flagella.
N-glycosylation, a posttranslational modification required for the accurate folding and stability of many proteins, has been observed in organisms of all domains of life. Although the haloarchaeal S-layer glycoprotein was the first prokaryotic glycoprotein identified, little is known about the glycosylation of other haloarchaeal proteins. We demonstrate here that the glycosylation of Haloferax ...
متن کاملIsolation and characterization of flagella and flagellin proteins from the Thermoacidophilic archaea Thermoplasma volcanium and Sulfolobus shibatae.
Isolated flagellar filaments of Sulfolobus shibatae were 15 nm in diameter, and they were composed of two major flagellins which have M(r)s of 31,000 and 33,000 and which stained positively for glycoprotein. The flagellar filaments of Thermoplasma volcanium were 12 nm in diameter and were composed of one major flagellin which has an M(r) of 41,000 and which also stained positively for glycoprot...
متن کاملPro-Inflammatory Flagellin Proteins of Prevalent Motile Commensal Bacteria Are Variably Abundant in the Intestinal Microbiome of Elderly Humans
Some Eubacterium and Roseburia species are among the most prevalent motile bacteria present in the intestinal microbiota of healthy adults. These flagellate species contribute "cell motility" category genes to the intestinal microbiome and flagellin proteins to the intestinal proteome. We reviewed and revised the annotation of motility genes in the genomes of six Eubacterium and Roseburia speci...
