Crystal structure of lignin peroxidase.
The crystal structure of lignin peroxidase (LiP) from the basidiomycete Phanerochaete chrysosporium has been determined to 2.6 A resolution by usine multiple isomorphous replacement methods and simulated annealing refinement. Of the 343 residues, residues 3-335 have been accounted for in the electron density map, including four disulfide bonds. The overall three-dimensional structure is very si...
متن کاملLignin peroxidase structure and function.
Lignin peroxidase (LiP) plays a central role in the biodegradation of the plant cell wall constituent lignin. LiP is able to oxidize aromatic compounds with redox potentials higher than 1.4 V (NHE) by single electron abstraction, but the exact redox mechanism is still poorly understood. The finding in our laboratory that the Cbeta-atom of Trp171 carries a unique modification led us to initiate ...
متن کاملLignin 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...
متن کاملThe crystal structure of cytochrome c peroxidase.
The three-dimensional conformation of yeast cytochrome c peroxidase has been determined from a 2.5 A electron density map computed with phases obtained from two isomorphous mercury derivatives. Partial sequence information that has recently become available aided in completion of the tracing of the polypeptide backbone, confirmed the presence of a proximal histidine heme ligand and aided in ide...
متن کاملLignin 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...
