Azospirillum brasilense can display a single polar flagellum and several lateral flagella. The A. brasilense Sp7 gene laf1, encoding the flagellin of the lateral flagella, was isolated and sequenced. The derived protein sequence is extensively similar to those of the flagellins of Rhizobium meliloti, Agrobacterium tumefaciens, Bartonella bacilliformis, and(More)
Many bacterial species are motile by means of flagella. The structure and implantation of flagella seems related to the specific environments the cells live in. In some cases, the bacteria even adapt their flagellation pattern in response to the environmental conditions they encounter. Swarming cell differentiation is a remarkable example of this(More)
Rather recently it has become clear that prokaryotes (Archaea and Bacteria) are able to glycosylate proteins. A literature survey revealed the different types of glycoproteins. They include mainly surface layer (S-layer) proteins, flagellins, and polysaccharide-degrading enzymes. Only in a few cases is structural information available. Many different(More)
Hildegard of Bingen (1098–1179) is one of the most influential female authors of the Middle Ages. From the point of view of computational stylistics, the oeuvre attributed to Hildegard is fascinating. Hildegard dictated her texts to secretaries in Latin, a language of which she did not master all grammatical subtleties. She therefore allowed her scribes to(More)
The induction of the lateral flagella of Azospirillum brasilense Sp7 was studied by using a translational fusion between the laf1 promoter and gusA. The fusion was induced when cells were grown on solid media but not when they were grown in broth. The fusion was also induced by incubation of liquid-grown cells with an anti-polar flagellum polyclonal(More)
