General description

SAICAR (a ribotide) can lose its phosphate group leading to the appearance of a riboside known as succinylaminoimidazolecarboxamide riboside (SAICAriboside or SAICAr) in cerebrospinal fluid, in urine, and, to a lesser extent, in plasma. SAICAriboside is characteristic of ADSL, a heritable deficiency of the enzyme adenylosuccinate lyase (ASL or adenylosuccinase) responsible for metabolizing SAICAR (SZMP) to AICAR (ZMP) and adenylosuccinate (SAMP) to AMP. ASL deficiency causes increased SAICAR & SAMP, and their corresponding rephosphorylated products SAICAr & succinyladenosine (S-Ado).

Purine homeostasis is ensured through a metabolic network widely conserved from prokaryotes to humans. Purines can either be synthesized de novo, reused, or produced by interconversion of extant metabolites using the so-called recycling pathway. Although thoroughly characterized in microorganisms, such
