Purification and determination of the action pattern of Haliotis tuberculata laminarinase

Résumé

The major laminarinase activity (EC 3.2.1.39) from the gastropodean marine mollusc Haliotis tuberculata was purified to homogeneity by cation exchange chromatography and its action pattern was investigated by HPAEC-PAD analysis off the degradation of various laminarin samples. It consists of a 60 kDa protein capable of depolymerizing the unbranched portions of the beta-(1-->3), beta-(1-->6)-glucan, down to laminaritriose. The enzyme operates via a molecular mechanism retaining the anomeric configuration. As the purified protein does not cleave the beta-(1-->6) linkages, it can be used for the structural analysis of laminarins.
