Example sentences for: tyra

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

  • The Anabaena/Nostoc linkage group is additionally reminiscent of the B. subtilis supraoperon in the presence of aroB and tyrA . Although B. subtilis does not have aroA Iβ represented in its supraoperon (as do Anabaena and Nostoc ), aroA Iβ is the homology class (of three possible DAHP synthase homologs distributed in nature [ 25, 26, 27]) that is utilized by B. subtilis . A number of supraoperon gene insertions have occurred outside of the trp operon as well.

  • 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.

  • As the prephenate dehydratase and prephenate dehydrogenase activities associated with the cytoplasmic AroQ•PheA and AroQ•TyrA proteins were not detected in this fraction, contamination with cytoplasmic species of AroQ was less than 1%.

  • 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).

  • The additional TyrA (p) present only in Anabaena and Nostoc and located as the carboxy-terminal gene of the supraoperon exhibits identities of 39-43% with the TyrA (p) proteins of some enteric bacteria.
