Significant increases in potato Starch-Synthase and Starch-Branching-Enzyme activities by dilution with buffer containing dithiothreitol and polyvinyl alcohol 50 K.

We have recently found that the dilution of purified potato Starch-Synthases (SS) and Starch-Branching-Enzymes (SBEs), by a glycine buffer (pH 8.5), containing 1.0mM dithiothreitol (DTT) and 0.
