title: Complete nucleotide sequence of cDNA and deduced amino acid sequence of rat liver arginase.
abstract: Arginase (EC 3.5.3.1) catalyzes the last step of urea synthesis in the liver of ureotelic animals. The nucleotide sequence of rat liver arginase cDNA, which was isolated previously (Kawamoto, S., Amaya, Y., Oda, T., Kuzumi, T., Saheki, T., Kimura, S., and Mori, M. (1986) Biochem. Biophys. Res. Commun. 136, 955-961) was determined. An open reading frame was identified and was found to encode a polypeptide of 323 amino acid residues with a predicted molecular weight of 34,925. The cDNA included 26 base pairs of 5'-untranslated sequence and 403 base pairs of 3'-untranslated sequence, including 12 base pairs of poly(A) tract. The NH2-terminal amino acid sequence, and the sequences of two internal peptide fragments, determined by amino acid sequencing, were identical to the sequences predicted from the cDNA. Comparison of the deduced amino acid sequence of the rat liver arginase with that of the yeast enzyme revealed a 40% homology.
