  • TyrR is a transcriptional regulator (TyrR) that controls the metabolism of aromatic amino acids in Escherichia coli . (frontiersin.org)
  • Glutamate plays an important role in protein metabolism since it serves as the main medium in amino-N exchange and is readily converted into other non-essential amino acids. (karelsavry.us)
  • However, as discussed earlier, the maintenance requirement for nonessential N is relatively high and the synthesis of some non-essential or semi-essential amino acid(s) may not be sufficient to meet endogenous losses and specific requirements not related to protein metabolism. (karelsavry.us)
