Example sentences for: maritima
How can you use “maritima” in a sentence? Here are some example sentences to help you improve your vocabulary:
For example, the mesophilic euryarchaeon Halobacterium sp. has more genes in common with the mesophilic Bacteria than does the thermophilic crenarchaeote Aeropyrum pernix . However, the extremophilic euryarcheote Archaeoglobus fulgidus shares many more genes with the extremophilic bacteria, Aquifex aeolicus and Thermotoga maritima than does Halobacterium . While this example illustrates the web-like relationships among genomes, recent phylogenetic reconstructions from molecular data have explored only few alternatives to the tree-paradigm (e.g.
The two free-living bacteria with small genomes, the hyperthermophiles A. aeolicus and T. maritima, did not join either the free-living or the parasitic bacterial cluster, despite their small number of genes similar to that in bacterial parasites (Fig.
It has been suggested that the mechanisms of these two enzymes may be different [ 33 ] . Direct interaction between the enzyme and the passing strand may not be necessary for the T. maritima topoisomerase I activity.
The bacterial side of this tree consists of three major clades: i) proteobacterial clade that, in addition to bona fide Proteobacteria, includes also A. aeolicus, M. tuberculosis, D. radiodurans, and Synechocystis sp, ii) Gram-positive clade that additionally includes T. maritima, and iii) an unexpected clade that unites spirochetes and chlamydia.
The hyperthermophilic topoisomerase I from Thermotoga maritima has been shown to coordinate one Zn(II) with a unique tetracysteine motif Cys-X-Cys-X 16 -Cys-X-Cys but Zn(II) binding is not required for relaxation activity [ 33 ] . The sequence of this unique tetracysteine motifs is somewhat different from those present in other type IA topoisomerases in that the other tetracysteine motifs always had at least two amino acids separating the pairs of cysteines (Cys-X 2-11 -Cys), instead of just one amino acid (Cys-X-Cys) in T. maritima topoisomerase I [ 33 ] . Therefore the structure and function of the single Zn(II) binding motif in T. maritima may differ from the multiple Zn(II) binding motifs in E. coli topoisomerase I. Direct interaction between DNA and the T. maritima Zn(II) binding motif has not been demonstrated.
