How can you use “arob” 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.

  • 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 supraoperonic AroB proteins occupy a tree position that is not particularly close to other AroB proteins (the closest matches being on the order of 30-35% identity with some enteric bacteria).

  • AroB sequences in nature are rather divergent.

  • 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.
