Pseudomonas syringae pv. phaseolicola , a plant pathogenic pseudomonad, possesses two sucrose‐splitting enzymes, a levansucrase and a sucrase. The levansucrase is found both extracellularly and intracellularly, and enzyme synthesis is independent of the carbon source. In addition to levansucrase, cells grown on sucrose contain a sucrase. The two sucrose‐splitting enzymes differ in their optimum pH value and optimum temperature as well as in their substrate specificities.
