CC -!- FUNCTION: Hydrolyzes sinigrin and, with lower efficiency, p-nitrophenyl
CC beta-D-glucoside. {ECO:0000269|PubMed:19703694}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a thioglucoside + H2O = a sugar + a thiol.; EC=3.2.1.147;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of terminal, non-reducing beta-D-glucosyl residues
CC with release of beta-D-glucose.; EC=3.2.1.21;
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=547 uM for sinigrin (at pH 4.5) {ECO:0000269|PubMed:19703694};
CC KM=80 mM for p-nitrophenyl beta-D-glucoside (at pH 4.5)
CC {ECO:0000269|PubMed:19703694};
CC Vmax=48.1 umol/min/mg enzyme with sinigrin as substrate (at pH 4.5)
CC {ECO:0000269|PubMed:19703694};
CC Vmax=17 umol/min/mg enzyme with p-nitrophenyl beta-D-glucoside as
CC substrate (at pH 4.5) {ECO:0000269|PubMed:19703694};
CC -!- TISSUE SPECIFICITY: Specifically expressed in roots.
CC {ECO:0000269|PubMed:19703694}.
CC -!- MISCELLANEOUS: It seems that the absence of a catalytic proton donor in
CC plant myrosinases is not impairing the hydrolysis of glucosinolates.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 1 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG52628.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
