Peroxidases lignin peroxidase

Fig. 2.11 Phylogeny of Class II of the peroxidase-catalase superfamily. Sequences coding for secretory fungal peroxidases lignin peroxidase (LiP), manganese peroxidase (MnP), and versatile peroxidase (VP) were used for this reconstruction. One of nine equally parsimonious trees is presented. Bootstrap values are indicated before slash, and Bayesian posterior probability values are indicated after the slash.

Unfortunately, not all PAHs are substrates for peroxidases. A correlation has been found between the ionization potential (IP) of PAHs and the specific activity of manganese peroxidase, lignin peroxidase, hemoglobin, and chloroperoxidase. A threshold value of IP was found for each enzyme. Lignin peroxidase oxidizes PAHs with IP = 7.55 eV [87], while manganese peroxidase oxidizes PAHs with IP...

Expression of lignin peroxidases in Phanerochaete chtysosporium is induced by nitrogen-limitation, and by the concentration of Mn (11) in the medium (Perez and Jeffries 1990). 

The inclusion of nitrate may lead to various complications, which have been discussed in Chapter 2. In addition, the nitrogen status of the growth medium determines the levels of lignin peroxidases and manganese-dependent peroxidases that are synthesized in Phanerochaete chrysosporium. The role of Mn concentration is noted later and in Chapter 3, Part 5.

The degradation of chlorinated phenols has been examined with the white-rot basidiomy-cete Phanerochaete chrysosporium under conditions of nitrogen limitation, and apparently involves both lignin peroxidase and manganese-dependent peroxidase activities (Valli and Gold 1991).
