How can you use “arob” in a sentence? Here are some example sentences to help you improve your vocabulary:
AroB sequences in nature are rather divergent.
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.
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 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.
