Products of the o-Toluidine oxidation with glucose oxidase and peroxidase

Could anybody describe which product is formed in the following reaction (o-Toluidine oxidation)? 


$$\ce{H2O2 + o-Toluidine\_{uncolored} - Peroxidase -> H2O + 1/2 O2 + o-Toluidine\; Oxidate\_{colored}} $$


**Note**: Hydrogen peroxide is one of the products of glucose oxidation to glucolactone by glucose oxydase.




The product most likely is 2-methylnitrobenzene (**3**), which means that the amino group ($\ce{-NH2}$) in o-toluidine (**1**) is oxidized to a nitro group ($\ce{-NO2}$). The oxidation proceeds via 2-methylnitrosobenzene (**2**).

The formation of 2-methylnitrobenzene can be detected photometrically at $\lambda$ = 400 nm, where the aniline does not absorb.
