  • Sucrose synthase (SuSy) plays an important role in sucrose degradation and occurs both as a soluble and as a membrane‐associated enzyme in higher plants. We show that membrane association can vary in vivo in response to gravistimulation, apparently involving SuSy dephosphorylation, and is a reversible process in vitro. Phosphorylation of SuSy has little effect on its activity but decreases its surface hydrophobicity as reported with the fluorescent probe bis‐ANS. We postulate that… CONTINUE READING
