Gene
RFS, Os01g0170000, LOC_Os01g07530, OJ1276_B06.38, OsJ_00538, P0583G08.2
Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Transglycosidase operating by a ping-pong reaction mechanism. Involved in the synthesis of raffinose, a major soluble carbohydrate in seeds, roots and tubers. Specific for galactinol and p-nitrophenyl-alpha-D-galactoside as galactosyl donors. Able to utilize sucrose, lactose, 4-beta-galactobiose, N-acetyl-D-lactosamine, trehalose and lacto-N-biose as acceptors. May also act as a glycoside hydrolase.1 Publication

Catalytic activityi

Alpha-D-galactosyl-(1->3)-1D-myo-inositol + sucrose = myo-inositol + raffinose.1 Publication

Enzyme regulationi

Inhibited by Ag2+, Hg2+, Zn2+, p-chloromercuribenzoate (pCMB) and 1-deoxygalactonojirimycin.

Kineticsi

    Vmax=25.6 nmol/sec/mg enzyme toward raffinose for the raffinose synthesis activity1 Publication

    Vmax=6.8 nmol/sec/mg enzyme toward p-nitrophenyl-alpha-D-galactoside for the hydrolysis activity

    Vmax=8.5 nmol/sec/mg enzyme toward galactinol for the hydrolysis activity

    Vmax=5.7 nmol/sec/mg enzyme toward raffinose for the hydrolysis activity

    pH dependencei

    Optimum pH is 7.0.

    Temperature dependencei

    Optimum temperature is 45 degrees Celsius.
