products description :
Description: OTC Recombinant produced in E Coli is a single polypeptide chain containing 347 amino acids (33-354) and having a molecular mass of 38.9kDa.OTC is fused to a 25 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Introduction: OTC is a member of the ATCase/OTCase family. OTC has a key part in the urea cycle, catalyzing the second step in this pathway: the transformation of L-orthinine and carbamoyl phosphate to L-citrulline. In humans, the urea cycle is a vital pathway to detoxification of ammonia. Alterations in the gene encoding OTC are linked to the X-linked disorder OTCD (ornithine carbamoyltransferase deficiency). OTCD disorder of the urea cycle is characterized by hyperammonemia.

ncbi summary :
This nuclear gene encodes a mitochondrial matrix enzyme. Missense, nonsense, and frameshift mutations in this enzyme lead to ornithine transcarbamylase deficiency, which causes hyperammonemia. Since the gene for this enzyme maps close to that for Duchenne muscular dystrophy, it may play a role in that disease also. [provided by RefSeq, Jul 2008]
uniprot summary :
OTC: Defects in OTC are the cause of ornithine carbamoyltransferase deficiency (OTCD). OTCD is an X- linked disorder of the urea cycle which causes a form of hyperammonemia. Mutations with no residual enzyme activity are always expressed in hemizygote males by a very severe neonatal hyperammonemic coma that generally proves to be fatal. Heterozygous females are either asymptomatic or express orotic aciduria spontaneously or after protein intake. The disorder is treatable with supplemental dietary arginine and low protein diet. The arbitrary classification of patients into the neonatal group (clinical hyperammonemia in the first few days of life) and late onset (clinical presentation after the neonatal period) has been used to differentiate severe from mild forms. Belongs to the ATCase/OTCase family. Protein type: Amino Acid Metabolism - arginine and proline; Mitochondrial; Transferase; EC 2.1.3.3. Chromosomal Location of Human Ortholog: Xp21.1. Cellular Component: mitochondrion; mitochondrial matrix; mitochondrial inner membrane.
