Specific activities of B. adusta, P. eryngii, and P. chrysosporium peroxidases with selected azo and phthalocyanine dyes^a

Prepn	Sp act (U/mg) with:
	Azo dyes				Phthalocyanine dyes
	RV5	RB5	RO96	RR198	RB38	RB15
B. adusta MnP1	6.6	6.1	5.8	3.2	7.2	9.7
P. eryngii MnPL1	8.2	5.4	6.8	3.7	9.3	10.8
P. eryngii MnPL2	8.1	5.4	8.1	3.2	10.0	10.9
P. chrysosporium MnP1	0.09	Nb	N	N	0.22	0.12
P. chrysosporium MnP1 + 0.3 mM MnSO4	0.46	N	N	N	N	N
B. adusta LiP2	0.2	0.3	0.13	0.09	0.67	1.1
B. adusta LiP2 + 2 mM veratryl alcohol	5.6	5.1	3.9	9.6	5.3	9.5

^aThe reaction mixtures contained 0.1 mM H₂O₂ and 0.1 M tartrate at pH 3.5 (azo dyes) or pH 3.75 (phthalocyanines). For the MnP reactions dye concentrations of 30 μM (azo dyes) and 20 μM (phthalocyanines) were used. In the case of LiP reactions a lower dye concentration (10 μM) was used to avoid inhibition by high substrate concentrations. 

^bN, negligible (<10⁻³ U/mg).
