additional information EC 1.4.1.31 and EC 1.4.1.30 catalyse the same reaction but with different quantitative specificity, EC 1.4.1.30 phosphorolyzes laminaritriose and higher homologues at a greater rate than laminaribiose while the opposite behaviour is observed with EC 1.4.1.31 Euglena gracilis ?
