General annotation (Comments)

Function

Hydrolyzes sinigrin and, with lower efficiency, p-nitrophenyl beta-D-glucoside. Ref.5

Catalytic activity

A thioglucoside + H2O = a sugar + a thiol.

Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose.

Tissue specificity

Specifically expressed in roots. Ref.5

Miscellaneous

It seems that the absence of a catalytic proton donor in plant myrosinases is not impairing the hydrolysis of glucosinolates.

Sequence similarities

Belongs to the glycosyl hydrolase 1 family.

Biophysicochemical properties

Kinetic parameters:

KM=547 µM for sinigrin (at pH 4.5) Ref.5

KM=80 mM for p-nitrophenyl beta-D-glucoside (at pH 4.5)

Vmax=48.1 µmol/min/mg enzyme with sinigrin as substrate (at pH 4.5)

Vmax=17 µmol/min/mg enzyme with p-nitrophenyl beta-D-glucoside as substrate (at pH 4.5)

Sequence caution

The sequence AAG52628.1 differs from that shown. Reason: Erroneous gene model prediction.
