| Abstract: | The alga Polytoma uvella was found to be a good source of both soluble and starch-bound NDPG-glucosyltransferase. The properties of the enzymes were similar to those of transferases from other plant sources, but differed in some respects. ADPG and UDPG acted as glucose donors, while maltose was inactive as glucose acceptor. Acetone preparations of the soluble enzyme were stable, but β-amylase could not be completely removed without inactivating the transferase. They also contained oligosaccharides of the maltose series. |
