ZUSAMMENFASSUNG

Purple acid phosphatase (PAP) was purified from sweet potato dry powder, which is used as a food additive. Spectrometric and enzymatic analyses, and analysis of the amino-terminal sequence indicated that the purified purple acid phosphatase was PAP1. High activity in neutral and acidic conditions, broad substrate specificity, and good thermal stability of PAP1 suggest the possibility of practical applications of PAP1.
