Abstract
Acid phosphatases (orthophosphoric-monoester phosphohydrolases, acid optimum, EC 3.1.3.2) of low MW were isolated from cytosol and chromatin of rat liver cells. The cytosolic enzyme was homogeneous on SDS[sodium dodecylsulfate]-polyacrylamide-gel electrophoresis at pH 8.3 (MW 16,000 .+-. 3000). Both enzymes showed similar electrophoretic mobility and MW but they differed in substrate specificity, response to inhibitors and susceptibility to SH-protecting reagents.
