Arginase in bull testis.
Bull testis arginase was about 1,000 times purified. The molecular weight was estimated to 120,000 (+/- 250). The enzyme was an anionic protein. Km was determined to be 3.4 mM. According to electrophoretic mobility and affinity to DEAE-cellulose as well as to the immunological properties, the arginase isolated from bull testis may be identified as arginase A1.
