4335 SAICAR SAICAR (or (S)-2-[5-Amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido]succinate) is a substrate for the multifunctional protein ADE2. SAICAR is an intermediate in purine metabolism. (S)-2-[5-Amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido]succinate is converted from 5-Amino-1-(5-phospho-D-ribosyl) imidazole-4-carboxylate via phosphoribosylaminoimidazole-succinocarboxamide synthase [EC: 6.3.2.6] or SAICAR synthase. This enzyme catalyses the seventh step out of ten in the biosynthesis of purine nucleotides. The appearance of succinylaminoimidazolecarboxamide riboside (SAICAriboside) and succinyladenosine (S-Ado) in cerebrospinal fluid, urine, and to a lesser extent in plasma is characteristic of a heritable deficiency Adenylosuccinate lyase deficiency. . 3031-95-6 160666 C13H19N4O12P White powder. No indication of carcinogenicity to humans (not listed by IARC). This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation. Chronically high levels of SAICAR are associated with Adenylosuccinate Lyase Deficiency. 2014-08-29T06:13:39Z 2026-04-06T12:24:34Z C04823 18319 P-RIBOSYL-4-SUCCCARB-AMINOIMIDAZOLE true NC1=C(N=CN1[C@@H]1O[C@H](COP(O)(O)=O)[C@@H](O)[C@H]1O)C(=O)N[C@@H](CC(O)=O)C(O)=O C13H19N4O12P InChI=1S/C13H19N4O12P/c14-10-7(11(22)16-4(13(23)24)1-6(18)19)15-3-17(10)12-9(21)8(20)5(29-12)2-28-30(25,26)27/h3-5,8-9,12,20-21H,1-2,14H2,(H,16,22)(H,18,19)(H,23,24)(H2,25,26,27)/t4-,5+,8+,9+,12+/m0/s1 NAQGHJTUZRHGAC-ZZZDFHIKSA-N 454.2833 454.073708604 Endogenous Solid HMDB00797 141175 Shaw, Gordon; Thomas, Peter S.; Patey, Carole A.
