Protein attributes
| Sequence length | 541 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Degradation of glucosinolates (glucose residue linked by a thioglucoside bound to an amino acid derivative) to glucose, sulfate and any of the products: thiocyanates, isothiocyanates, nitriles, epithionitriles or oxazolidine-2-thiones. These toxic degradation products can deter insect herbivores. Seems to function in abscisic acid (ABA) and methyl jasmonate (MeJA) signaling in guard cells. Functionally redundant with TGG2. Hydrolyzes sinigrin and, with lower efficiency, p-nitrophenyl beta-D-glucoside. Ref.7 Ref.12 Ref.13 Ref.14 |
| Catalytic activity | A thioglucoside + H2O = a sugar + a thiol. Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose. |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Vacuole By similarity. |
| Tissue specificity | Expressed in guard cells, phloem-associated cells and myrosin cells. Ref.10 |
| 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=45 µM for sinigrin (at pH 4.5) Ref.13 KM=34 mM for p-nitrophenyl beta-D-glucoside (at pH 4.5) Vmax=2.3 µmol/min/mg enzyme with sinigrin as substrate (at pH 4.5) Vmax=1.2 µmol/min/mg enzyme with p-nitrophenyl beta-D-glucoside as substrate (at pH 4.5) |
