A particulate acid phosphatase (EC, orthophosphoric monoester phosphohydrolase (acid optimum)) was extracted in 1 M KCl, from 2-day rat epidermis. The enzyme has a Mr of 32,000, but two forms, F1 and F2 with pI values of 8.6 and 8.3, respectively, were identified while the pI values of other acid phosphatases soluble in sucrose and Triton X-100 were all acidic. F1 and F2 also differed from other epidermal acid phosphatases because they were (a) activated by Fe2+ and reducing agents, (b) showed immunological cross-reactivity with purple acid phosphatase of rat spleen and (c) dephosphorylated phosvitin and alpha-casein even though they had rather high Km values.
