Cloning and sequencing of the ornithine carbamoyltransferase gene from Pachysolen tannophilus.
A fragment of DNA from a yeast Pachysolen tannophilus, bearing the ornithine carbamoyltransferase gene (OCTase, EC 2.1.3.3) has been cloned from a genomic library by functional complementation of the Escherichia coli OCT-negative mutant. The gene was located within the cloned segment of DNA and its coding sequence identified by DNA sequencing. This has indicated that P. tannophilus OCT gene encodes a 347 amino acid polypeptide, which shows 60% identity to the homologous Saccharomyces cerevisiae protein. The amino acid composition of its N-terminus indicates that this protein is translocated across the mitochondrial membrane. The gene can be expressed in E. coli as well as in S. cerevisiae. Comparison with other OCTases confirms a high degree of conservation among these proteins.[1]References
