Example sentences for: trpr

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

  • A regulatory gene, the trpR repressor, precedes the tryptophan operon on the amino-terminal side.

  • Within the low-GC block, trpR is separated by four ORFs from genes encoding the two subunits of anthranilate synthase ( trpAa and trpAb ). These probably do not function for general tryptophan biosynthesis since paralogs of these genes, which exhibit a phylogenetically congruent context of gene organization, exist elsewhere in the genome (Figure 6).

  • A second paralog of the tryptophan synthase β subunit ( trpEb-2 ) is also present in an extra-operonic location several genes upstream of trpR.

  • The phylogenetic incongruence of trpR , a regulatory gene in Xylella fastidiosa , led to recognition of a low-GC gene block in X. fastidiosa.

  • Figure 4shows that trpR in X. fastidiosa is at one end of a block of seven genes, all of which have a distinctively low GC content (highlighted in green), compared to the flanking genes (highlighted in yellow).
