Example sentences for: tyra

How can you use “tyra” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • 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.

  • A different result was obtained for genes encoding AroB and TyrA.

  • 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).

  • These results for supraoperonic aroB and tyrA (p) could be consistent with LGT, but with no clear donor candidates available.

  • P. aeruginosa is similar to S. typhimurium in having an AroQ•PheA fusion in the cytoplasm as well as the periplasmic AroQ species (*AroQ), but differs in lacking the AroQ•TyrA fusion.
