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.
