摘要
1. Phanerochaete chrysosporium INA-12 secretes several lignin peroxidase isoenzymes. This paper reports an improved procedure for the purification of the different isoforms compared to those previously described. 2. Lignin peroxidases are first concentrated and prefractionated on fast-flow ion-exchangers which avoid concentration by ultrafiltration and dialysis. 3. Further purification is achieved by hydrophobic interaction chromatography and anion-exchange FPLC. 4. Two major forms were purified to homogeneity. Kinetic measurements and protein characterization (isoelectric points, phosphate content) suggest that they are similar to those produced by P. chrysosporium BKM strain.
