WebCatecholamine biosynthesis begins with uptake of the amino acid tyrosine (TYR) into the cytoplasm of sympathetic neurons, adrenomedullary cells, possibly para-aortic enterochromaffin cells, and specific centers in the brain. Tyrosine hydroxylase (TH) catalyzes the conversion of TYR to DOPA. This is the enzymatic rate-limiting step in ... WebThe evolution of metabolic pathways is discussed with reference to the biosynthesis of a number of vitamins and cofactors. Retrograde and patchwork models are highlighted and their relevance to our knowledge of pathway processes and enzymes is examined. Pathway complexity is explained in terms of the acquisition of broad specificity enzymes.
