Example sentences for: arob

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

  • These differ for Anabaena and Nostoc as depicted in Figure 2. Anabaena has genes encoding aph and a hypothetical gene (open reading frame (ORF)) inserted between aroB and the trpAa • trpAb fusion.

  • 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 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.

  • All of the cyanobacterial AroB proteins form a compact cluster in the AroB tree (including the non-operonic Anabaena/Nostoc aroB genes), except for those encoded by the Anabaena/ Nostoc supraoperons.

  • AroB sequences in nature are rather divergent.
