Phosphoribosylaminoimidazolesuccinocarboxamide
Phosphoribosylaminoimidazolesuccinocarboxamide
is an
intermediate
in the
formation
of
purines
. The
conversion
of
ATP
,
L-aspartate
, and
5-aminoimidazole-4-carboxyribonucleotide
to 5-aminoimidazole-4-
ribonucleotide
,
ADP
, and
phosphate
by
phosphoribosylaminoimidazolesuccinocarboxamide synthetase
represents the
eighth
step
of
de novo
purine nucleotide
biosynthesis
.
