Mammals contain two genes encoding distinct isoforms of arginase (arginases I and II), both of which catalyze the conversion of arginine to ornithine and urea. However, their subcellular localization and tissue-specific patterns of expression are very different, indicating that they perform distinct physiologic roles. As an initial step in elucidating the regulation and physiologic roles of arginase II, this report describes the characterization of a mammalian arginase II gene. The murine arginase II gene contains eight exons like the arginase I gene. The six internal exons have intron/exon boundaries that are identical to the arginase I gene; however, exon three of the arginase II gene has obtained a three-base-pair insertion. The identity of the exon/intron boundaries is consistent with a gene duplication as the origin of the arginase isozymes with the small insertion occurring after the duplicative event. The promoter region of the arginase II gene, which bears no resemblance to that of the arginase I genes, contains numerous potential binding sites for enhancer and promoter elements but does not contain a TATA box.
