| characterization of α2,3- and α2,6-sialyltransferases from helicobacter acinonychis. | genome sequence data were used to clone and express two sialyltransferase enzymes of the gt-42 family from helicobacter acinonychis atcc 51104, a gastric disease isolate from cheetahs. the deposited genome sequence for these genes contains a large number of tandem repeat sequences in each of them: hac1267 (rqkele)(15) and hac1268 (eekllefkni)(13). we obtained two clones with different numbers of repeat sequences for the hac1267 gene homolog and a single clone for the hac1268 gene homolog. both g ... | 2012 | 22504533 |
| the swimming behavior of selected archaea. | the swimming behavior of bacteria has been studied extensively, at least for some species like escherichia coli. in contrast alomost no data have been published for archaea in this respect. in a systematic study we asked how the archaeal model organisms halobacterium salinarum, methanococcus voltae, methanococcus maripaludis, methanocaldococcus jannaschii, methanocaldococcus villosus, pyrococcus furiosus and sulfolobus acidocaldarius swim and which swimming behavior they exhibit. the two euryarc ... | 2012 | 22247169 |
