Tryptophan Synthase: Biocatalyst Extraordinaire
WebQuestion: In E. coli, the tryptophan operon encodes structural genes, including trpC, trpB, and trpA, that encode the tryptophan synthetase protein complex. The operon also encodes a repressor protein, encoded by the trpR gene. In the presence of high levels of tryptophan, tryptophan molecules bond the repressor protein and allow the repressor to recognize … 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 … port parking space port canaveral
