Adenylosuccinate lyase (ADSL) is a bifunctional enzyme in de novo purine biosynthesis that catalyzes the conversion of adenylosuccinate to AMP and SAICAR to AICAR, linking nucleotide metabolism to cellular energy balance and proliferative capacity. By regulating pools of purine nucleotides and pathway intermediates, ADSL activity influences DNA/RNA synthesis, replication stress responses, and metabolic signaling in rapidly dividing cells. Loss-of-function variants in human ADSL disrupt purine homeostasis and are associated with adenylosuccinate lyase deficiency, a neurometabolic disorder characterized by accumulation of succinylpurines and impaired neurodevelopment. In research settings, ADSL is studied to dissect purinosome dynamics, metabolic control of gene expression, and the contribution of purine pathway perturbations to cellular stress phenotypes.
ADSL Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ADSL locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ADSL. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt ADSL function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of ADSL-disrupted clones.
