Protein
Sulfhydryl oxidase 2
Gene
QSOX2, At2g01270, F10A8.15
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Catalytic activityi

2 R'C(R)SH + O2 = R'C(R)S-S(R)CR' + H2O2.

Cofactori

FAD By similarity.
