TABLE 1.

Apparent K_m values for oxidation of the azo dyes RV5 and RB5 and the phthalocyanine complex RB38 by MnP isoenzymes from B. adusta and P. eryngii^a

Isoenzyme	Km (μM)
	RV5	RB5	RB38
B. adusta MnP1	11	6	6
P. eryngii MnPL1	16	4	8
P. eryngii MnPL2	12	4	7

^aThe reaction mixtures contained dye, 0.1 mM H₂O₂, and 0.1 M tartrate at pH 3.5 (RV5 and RB5) or pH 3.75 (RB38).
