2.4.1.4 additional information Synechococcus sp. the enzyme AMS exhibits multiple catalytic activities. Primarily, it can hydrolyze sucrose to glucose and fructose or transfer glucose from sucrose hydrolysis to another glucose or acceptormolecule. As a side reaction, it is also able to catalyze the isomerization of sucrose to turanose or trehalulose ?
