1. Chicken skeletal tartrate-sensitive (TsACP) and -resistant (TrACP) acid phosphatase isoenzymes could be separated from each other by carboxylmethyl-sepharose ion exchange chromatography. 2. Chicken skeletal TsACP showed a gradual time-dependent loss of sensitivity to tartrate inhibition when incubated at room temperature, but not at 4 degrees C. 3. The loss of sensitivity to tartrate inhibition was associated with an activation of the enzyme activity. 4. These changes were accompanied with a shift in the electrophoretic mobility of the enzyme activity from a large molecular sized form to a smaller molecular sized form that resembled the freshly prepared TrACP on the native acidic polyacrylamide electrophoresis gels, and on molecular sieve Superose-12 Fast Protein Liquid Chromatography. 5. Kinetic evaluations of the biochemical properties of the "converted" TsACP activity resembled the TrACP. 6. The apparent "conversion" was not unique to chicken TsACP, since similar "conversion" was observed with partially purified preparations of bovine bone matrix TsACP and of human osteoblastic TsACP. 7. Addition of several serine protease inhibitors did not prevent the "conversion". 8. These findings are consistent with the possibility that skeletal TsACPs are precursors of skeletal TrACPs.
