How can you use “iβ” in a sentence? Here are some example sentences to help you improve your vocabulary:
Accordingly, the 3:1 dinucleotide frequencies of the aroA Iβ - tyrA c gene block and the immediately flanking genes were analyzed, but these dinucleotide frequencies also did not suggest LGT.
A particularly fortuitous gene that could favor or disfavor the hypothesis of LGT of the aroA Iβ - tyrA (p) gene block in Anabaena/Nostoc is trpAa • trpAb , a fusion corresponding to two genes that are usually separate (free-standing).
Thus, Anabaena has two additional extra-operonic paralogs of aroA Iβ and trpD . In addition to extra-operonic, free-standing copies of trpAa and trpAb , a second fused gene ( trpAa • trpAb_2 ) encoding the two domains of anthranilate synthase is present in Anabaena . Nostoc has two extra-operonic copies of aroA Iβ , aroB and trpD . All cyanobacteria possess AroA of the Iβ class ( aroA Iβ ). While this is also true of the Anabaena/Nostoc lineage (in fact, having multiple copies), both Anabaena and Nostoc possess an additional gene encoding AroA of the Iα class ( aroA Iα ). All cyanobacteria possess a tyrA gene of the arogenate-specificity class ( tyrA a ), but the Anabaena/Nostoc supraoperons also possess a tyrA gene deemed to be a cyclohexadienyl dehydrogenase [ 28] with a favored specificity for prephenate ( tyrA (p) ) (C.A.B.
Of course, the spatial location of *Aat Iβ in the periplasm would seem to rule out in vivo function in histidine biosynthesis.
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.
