WebIntroduction and Summary. Tryptophanyl-tRNA synthetase represents perhaps the most recent addition to the genetic code. It is a class I aminoacyl-tRNA synthetase (aaRS) that seems to break the symmetry of the class-specific hierarchy, 1 there being only a single member of sub-class IIc (PheRS), while sub-class Ic includes the aminoacyl tRNA … Web8. Tryptophan synthetase of E.coli, a typical bifunctional oligomeric enzyme consists of (a) a protein A and one subunit A (b) a protein designated A (c) two proteins designated A and B (d) a protein designated B. Answer: (c) 9. This statement about enzymes is true (a) enzymes accelerate reactions by lowering the activation energy

As an essential amino acid, tryptophan is not synthesized from simpler substances in humans and other animals, so it needs to be present in the diet in the form of tryptophan-containing proteins. Plants and microorganisms commonly synthesize tryptophan from shikimic acid or anthranilate: anthranilate condenses with phosphoribosylpyrophosphate (PRPP), generating pyrophospha…
