Sucrose metabolism in green algae. I. The presence of sucrose synthetase and sucrose phosphate synthetase.

The presence of sucrose synthetase and sucrose phosphate synthetase has been demonstrated in two species of green algae: Chlorella vulgaris and Scenedesmus obliquus. Partial purification from crude extracts allowed the determination of the kinetic constants of algae enzymes. They are very similar to the ones reported for enzymes from higher plants.
