Deoxyribonuclease I (DNase I) was purified 26500-fold in 39% yield from porcine pancreas to electrophoretic homogeneity using three-step column chromatography. The purified enzyme was inhibited by an antibody specific to the purified enzyme but not by G-actin. A 1303 bp cDNA encoding porcine DNase I was constructed from total RNA from porcine small intestine using a rapid amplification of cDNA ends method, followed by sequencing. Mature porcine DNase I protein was found to consist of 262 amino acids. Unlike all other mammalian DNase I enzymes that are inhibited by G-actin, porcine DNase I has H65 and S114 instead of Y65 and A114, which presumably results in the lack of inhibition. Porcine DNase I was more sensitive to low pH than rat or bovine enzymes. Compared with their primary structures, the amino acid at position 110 was N in porcine enzyme, but S in rat and bovine enzymes. A porcine mutant enzyme in which N was substituted by S alone at position 110 (N110S) became resistant to low pH to a similar extent as the rat and bovine enzymes.
