Argininosuccinate synthetase and argininosuccinate lyase: two ornithine cycle enzymes from Agaricus bisporus

, 2007
Accumulation of high quantities of urea in fruiting bodies is a known feature of larger basidiomycetes. Argininosuccinate synthetase (ASS) and argininosuccinate lyase (ASL) are two ornithine cycle enzymes catalysing the last two steps in the arginine ...

Differential inhibition of 17alpha-hydroxylase and 17,20-lyase activities by three novel missense CYP17 mutations identified in patients with P450c17 deficiency [PDF]

, 2002
The microsomal enzyme cytochrome P450c17 is an important regulator of steroidogenesis. The enzyme has two functions: 17alpha-hydroxylase and 17,20-lyase activities.

Interference with the citrulline-based nitric oxide synthase assay by argininosuccinate lyase activity in Arabidopsis extracts

, 2007
There are many reports of an arginine-dependent nitric oxide synthase activity in plants; however, the gene(s) or protein(s) responsible for this activity have yet to be convincingly identified.

MRI findings of hypomyelination in adenylosuccinate lyase deficiency

, 2019
Adenylosuccinate lyase deficiency is a rare genetic disorder with few reported cases in the United States. Magnetic resonance imaging findings in the brain include hypomyelination and low generalized parenchymal volume.

Unstable argininosuccinate lyase in variant forms of the urea cycle disorder argininosuccinic aciduria [PDF]

, 2021
Loss of function of the urea cycle enzyme argininosuccinate lyase (ASL) is caused by mutations in the ASL gene leading to ASL deficiency (ASLD). ASLD has a broad clinical spectrum ranging from life-threatening severe neonatal to asymptomatic forms ...

Ornithine cycle in Nostoc PCC 73102: Presence of an in vitro functional argininosuccinate lyase

, 1997
The presence of argininosuccinate lyase (ASL), an enzyme catalyzing the final step of arginine biosynthesis, was demonstrated in the heterocystous cyanobacterium Nostoc PCC 73102 by measuring in vitro enzyme activity and by visualization of ASL in ...
