Example sentences for: cyanobacterial
How can you use “cyanobacterial” in a sentence? Here are some example sentences to help you improve your vocabulary:
All of the cyanobacterial AroB proteins form a compact cluster in the AroB tree (including the non-operonic Anabaena/Nostoc aroB genes), except for those encoded by the Anabaena/ Nostoc supraoperons.
Using a query set containing six group 1 sequences, seven group 2 sequences, seven group 3 sequences, and four cyanobacterial sequences, Block Maker identified three blocks of conserved sequence (Figure 3).
As BLAST hits must be considered imperfect indicators of nearest-neighbor homologs [ 38], the conclusion that the operonic trp -pathway genes are of cyanobacterial lineage origin was confirmed more rigorously by examination of extensive trees (available upon request) constructed for each trp protein of Anabaena and Nostoc . For the Trp-pathway proteins, all the cyanobacterial proteins clustered together, regardless of whether they were Anabaena or Nostoc paralogs or whether they were the singly represented proteins of Synechocystis, Synechococcus , or Prochlorococcus . The same result was obtained for AroA Iβ protein trees.
In each case Prochlorococcus marinus and Synechococcus species are the outlying sequence group, with the other cyanobacterial sequences ( Nostoc punctiforme and Anabaena species) being closer to the higher plant sequences from A. thaliana and corn ( Zea mays ). The order of branching shown is supported by very high bootstrap values.
This implies that the cyanobacteria probably acquired these forms of the PRC-barrel through lateral transfer from the purple bacteria and may have incorporated them as regulatory subunits into the organizationally distinct cyanobacterial photosystems [ 29, 30, 31] or into other uncharacterized electron-transfer chains.
