title: Copurification of L-ascorbate-2-sulfate sulfohydrolase and arylsulfatase activities from the liver of a marine gastropod, Charonia lampas.
abstract: Ascorbate-2-sulfate sulfohydrolase was purified 184-fold from a crude extract of the liver of Charonia lampas.  In all purification steps including phosphocellulose, first and second Sephadex G-150 column chromatographies, the enzyme activity eluted together with arylsulfatase [ED 3.1.6.1] activity, and was separated from glycosulfatase ]EC 3.1.6.3] activity.  The nonidentity of ascorbate-2-sulfate sulfohydrolase and glycosulfatase was further confirmed by an isoelectric focussing study.  Ascorbate-2-sulfate sulfohydrolase had an isoelectric point, pI, of 4.9, and had maximum activity at pH 4.0.  Its molecular weight was estimated to be about 154.000.
