Molecular definition of bovine argininosuccinate synthetase deficiency.
Citrullinemia is an inborn error of metabolism due to deficiency of the urea cycle enzyme, argininosuccinate synthetase [L-citrulline:L-aspartate ligase (AMP-forming), EC 6.3.4.5]. The disease was first described in humans but was recently reported in dairy cattle in Australia. Here we report the nucleotide sequence of the normal bovine cDNA for argininosuccinate synthetase and the mutation pre...
متن کاملMolecular analysis of argininosuccinate synthetase deficiency in human fibroblasts.
We have analyzed cultured skin fibroblasts derived from patients with argininosuccinate synthetase deficiency for alterations in gene structure, mRNA content, and protein structure. Genomic DNA was digested with the endonucleases EcoRI or HindIII, and the fragments were analyzed by Southern blotting and hybridization with a cDNA probe for argininosuccinate synthetase. The blot pattern is comple...
متن کاملArgininosuccinate synthetase of bovine liver: chemical and physical properties.
Homogeneous crystalline argininosuccinate synthetase [L-citrulline:L-aspartate ligase (AMP-forming), EC 6.3.4.5] prepared from bovine liver according to Rochovansky et al. [Rochovansky, O., Kodowaki, H. & Ratner, S. (1977)J. Biol. Chem. 252, 5287-5294] has been characterized with respect to amino acid composition and other chemical and physical properties. The total residue molecular weights de...
متن کاملArgininosuccinate synthetase deficiency: mutation analysis in 3 Thai patients.
Remarkable improvements in public health, nutrition, hygiene, and availability of medical services in the last 20 years have significantly reduced infant and childhood mortality in Thailand. Therefore, many rare and previously unidentified genetic disorders, which, in the past, usually led to the death of affected infants before a definitive diagnosis, have now been increasingly recognized. Rec...
متن کاملNitro analogs of substrates for argininosuccinate synthetase and argininosuccinate lyase.
The nitro analogs of aspartate and argininosuccinate were synthesized and tested as substrates and inhibitors of argininosuccinate synthetase and argininosuccinate lyase, respectively. The Vmax for 3-nitro-2-aminopropionic acid was found to be 60% of the maximal rate of aspartate utilization in the reaction catalyzed by argininosuccinate synthetase. Only the nitronate form of this substrate, in...
