Purine biosynthesis is a ten step process involving formation of common intermediate Inosine. Catabolic reactions are reverse of anabolic ones except that intermediates are not orotic acid derivatives. You can change your ad preferences anytime. Catabolism of the pyrimidine nucleotides leads ultimately to β-alanine (when CMP and UMP are degraded) or β-aminoisobutyrate (when dTMP is degraded) and NH 3 and CO 2. Electrons from the substrates are passed to molybdenum, FAD, iron and finally molecular oxygen which is reduced to hydrogen peroxide. Guanine and hypoxanthine have two fates: conversion to 5’ ribonucleotides or xanthine. The end product of purine catabolism … The end products of purine catabolism are different in dif-ferent species. The basis for this "fixed" concentration of nucleotides is that de novo synthesis and salvage pathways are very rigidly controlled under normal conditions. Excess pyrimidine degradation occurs during fast cell destruction as in leukemia or in patients undergoing radiation therapy. When purine synthesis is required by the cell, the enzymes of the purine synthesis pathway associate with one another to form purinosome complexes in order to promote substrate channeling. Nucleotides are synthesized from 5-C sugars and amino acids. Pyrimidine Catabolism Steps. Synthesis from amphibolic intermediates ( synthesis de novo ). De novo nucleotide biosynthesis requires a common precursor 5-Phosphoribosyl-1-pyrophosphate which is synthesized from a ribose-5-phosphate from pentose phosphate pathway.

Catabolism of purine nucleotides ultimately leads to the production of uric acid. Adenine and guanine nucleotides are derived from a common precursor, inosine monophosphate (IMP), which consists of ribose phosphate and a purine derivative known as hypoxanthine. CPS I is mitochondrial, used in urea synthesis, activated by N-acetyl glutamate and uses ammonia as N-source while CPS II is cytoplasmic, used for pyrimidine synthesis, inhibited by CTP and uses glutamine as N-source. This enzyme is found in liver and intestinal mucosa. Loss of uricase in hominids (humans, chimpanzees and gorillas) during evolution is proposed to be advantageous since uric acid is powerful antioxidant and scavanger of singlet oxygen and radicals, thus prolonging life and decreasing age related cancer rates.
