Effect of 1,5-gluconolactone on the formation of a glucoprotein in potato tuber

The occurrence of a two-step mechanism for the synthesis of a protein bound glucan in potato tuber was confirmed based on a different behaviour of the engaged enzymes towards 1,5-D-gluconolactone. The absence of [14C]erythritol after Smith periodate degradation of the labelled product synthesized du...
