ornithine transcarbamoylase

or·ni·thine car·bam·o·yl·trans·fer·ase

an enzyme catalyzing formation of l-citrulline and orthophosphate from l-ornithine and carbamoyl phosphate; a part of the urea cycle; a deficiency of this enzyme will result in ammonia intoxication and impaired urea formation.

Primary causes of hyperammonemia include congenital enzymopathies in the urea cycle, such as deficiencies of ornithine transcarbamoylase and argininosuccinate lyase.
For fluorescence PCR analysis of the 9-bp deletion, we prepared two PCR primers (9Del-AS and 9Del-AS; Table 1), and three templates; two were the reverse transcription products of the total RNA isolated from the liver of a patient with CPS1 deficiency and a patient with ornithine transcarbamoylase deficiency (as a control); a plasmid containing the homozygous 9-bp deletion mutation was used.
