Example sentences for: arob

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

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

  • Nostoc has frnE (encoding a thiol-disulfide isomerase) inserted between tyrA (p) and aroB . Four subclasses of tyrA are defined according to the substrate specificities of the TyrA gene product: tyrA p , specific for prephenate; tyrA a , specific for arogenate; tyrA c , accepts either prephenate or arogenate; and tyrA (p) , has broad specificity but exhibits a distinct preference for prephenate.

  • 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.

  • The common-pathway enzymes through chorismate synthase are named in order, that is [AroA] catalyzes the first pathway reaction, [AroB] the second, and so on.

  • The genes comprising the supraoperon of B. subtilis are aroG → aroB → aroH → trpAaBDCEbEa → hisH b → tyrA p → aroF . A hierarchy of internal promoters and terminators exists for differential control of the B. subtilis supraoperon.
