Phosphorylase II from potato tuber has been subjected to several purification procedures in order to: (a) separate the unprimed activity from the primed one coexisting in the enzymatic preparation, and (b) eliminate endogenous glucan and/or glycoprot

Disrupted potato starch granules obtained in the presence of 8 M urea were shown to increase [ 14 C] glucose incorporation from labeled ADP-glucose or UDP-glucose into starch, as compared to intact grains. Labeled glucose or maltose units were found

1. 1. A non-sedimentable fraction of potato tuber has been found to catalyze [ 14 C] glucose transfer from [ 14 C] glucose 1-phosphate to an endogenous proteic acceptor in the absence of added primer. This transfer is activated by Mn 2+ . 2. 2. The l

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 [ 14 C]erythritol after Smith periodat

The effect of spermine on particulate ADP-glucose: starch synthetase from the developing embryo of sweet corn has been studied. Spermine induces a considerable increase of glucose incorporation from ADP-glucose into the starch granules. The change in

Envelope membranes were isolated from potato tuber amyloplast by a discontinuous sucrose density gradient and high speed centrifugation. These membranes catalyzed the transfer of [14C]glucose from UDP-[14C]glucose to endogenous sterol acceptors and,

The glycosylating activities of two enzymatic preparations from potato tubers were compared, using β-sitosterol and β-solanidine as substrate. The 25 000 g fraction synthesized steryl glucoside (SG) and acylsteryl glucoside (ASG) when β-sitosterol

Steryl glucoside (SG) and acylated steryl glucoside (ASG) synthesis was investigated in amyloplast membranes from young, intermediate and mature potato tubers. The synthesis ratio SG/ASG was lowest in young tubers (3:2) and highest in mature tubers (

Incubation of potato tuber phophorylase II with [ 14 C]glucose 1-phosphate in the absence of an exogenous acceptor results in the synthesis of a radioactive product, presumably a protein-bound glucan. The carbohydrate moiety of this product was shown
