The characteristics of acid esterase from the patient with Wolman's disease, a rare familial lipidosis, were studied. Enzymatic analysis as well as mineral analysis were performed on the patient's liver, spleen, and adrenal glands. Acid esterase was low in the patient's leucocytes and other affected tissues. Further enzymatic study with subcellular fractions of the liver in both patient and control subject revealed that acid esterase was mostly localized in the membrane of lysosomes. The lysosomal esterase was unaffected by Ca2+, Mg2+, EDTA, E600 (microsomal esterase inhibitor), and it was less inhibited by NaCl than other fractions. Studies with those inhibitors showed that acid esterase has different properties compared to other lipases, such as lipoprotein lipase, adipose tissue lipase, and hepatic microsomal lipase. Studies with inhibitors also gave a negative view on a possible suppressive interaction of the high content of calcium in the target organs with acid esterase in Wolman's disease.
