No evidence for lignin peroxidase genes in ectomycorrhizal fungi

Ectomycorrhizal fungi in mineral soil

Ectomycorrhizal fungi are mutualistic symbionts of many forest trees and play a major role in nutrient uptake. They form diverse communities in boreal forest soils but functional differences within this group of fungi remain largely unknown. We study ectomycorrhzal fungi in mineral soil to determine how abiotic preferences influence their spatial distribution in stratified soil profiles. This i...

Genomic organization of lignin peroxidase genes of Phanerochaete chrysosporium.

Three lignin peroxidase (LiP) genes from the basidiomycete Phanerochaete chrysosporium were cloned on a single 30 kb cosmid insert. One gene, GLG5, is the genomic equivalent of a previously reported cDNA clone, CLG5. The other two LiP genes are transcriptionally convergent and map to a position approximately 15 kb downstream of GLG5. The translational stop codons of these genes are separated by...

Lignin Peroxidase Compound III

Lignin peroxidase compound III (LiPIII) was prepared via three procedures: (a) ferrous LiP + O2 (LiPIIIa), (b) ferric LiP + 0; (LiPIIIb), and (c) LiP compound II + excess HzOz followed by treatment with catalase (LiPIIIc). LiPIIIa, h, and c each have a Soret maximum at -414 nm and visible hands at 543 and 578 nm. LiPIIIa, b, and c each slowly reverted to native ferric Lip, releasing stoichiomet...

Lignin Peroxidase Of

Ligninase is a generic name for a group of isozymes that catalyze the oxidative depolymerization of lignin. Although undoubtedly produced by other lignin-degrading fungi, these isozymes to data have been isolated only from the basidiomycete Phanerochaete chrysosporium Burds. 1,2 These ligninases are extracellular and are produced during secondary metabolism, brought about by nutrient starvation...
