Example sentences for: trpab

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

  • Genes encoding the two anthranilate synthase subunits ( trpAa and trpAb ) and aryl-CoA ligase ( acl ) surely belong to an operon, as translational coupling is evident from the overlap of start and stop codons (Figure 4).

  • As only a limited number of trpAa • trpAb fusions are known, possible LGT donors can be evaluated.

  • Direct comparison of chlamydial trpAa and trpAb genes with those of the Xylella operon is not possible because all chlamydial genomes thus far mapped lack trpAa and trpAb [ 23].

  • 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).

  • Thus, in X. fastidiosa the incongruous phylogenetic position of trpR , the redundancy of the trp -linked genes encoding trpAa and trpAb , and the distinct phylogenetic incongruence of the latter gene pair all supported a reasonable possibility of origin by LGT.
