Datasheet:

S-NI catalyzes the irreversible decomposition of sucrose into fructose and glucose under neutral

conditions, and is one of the key enzymes for sucrose metabolism in soil microorganisms.

S-NI catalyzes the degradation of sucrose to produce reducing sugar, and further reacts with 3,5-

dinitrosalicylic acid to form brownish red amino compound, which has characteristic light absorption at

540 nm, and the increase rate of light absorption at 540 nm in a certain range is in direct proportion to NI

activity. Within a certain range the activity of S-NI is calculated by the increasing rate of light absorption.

Reagents and Equipment Required but Not Provided

Spectrophotometer, centrifuge, water-bath, transferpettor, 1 mL glass cuvette, mortar, toluene, sieve (30-

50 mesh) and distilled water.
