(redirected from argininosuccinase)

ar·gi·ni·no·suc·ci·nate ly·ase

(ar'ji-ni-nō-sŭk'si-nāt lī'ās),
An enzyme cleaving l-argininosuccinate nonhydrolytically to produce l-arginine and fumarate; a deficiency of this enzyme leads to argininosuccinoaciduria; catalyzes a step in the urea cycle.
Synonym(s): argininosuccinase
