| cellobiose oxidase from phanerochaete chrysosporium. stopped-flow spectrophotometric analysis of ph-dependent reduction. | cellobiose oxidase (cbo) from phanerochaete chrysosporium can utilize dichlorphenol-indophenol (cl2ind) and cytochrome c as effective electron acceptors for the oxidation of cellobiose. however, the ph dependencies of activity for these electron acceptors are significantly different. both compounds act as effective electron acceptors at ph 4.2, whereas only dichlorophenol-indophenol is active at ph 5.9. to explain this discrepancy, the ph dependencies of the reduction rates of fad and heme, resp ... | 1992 | 1321733 |
| effect of white rot basidiomycetes on chemical composition and in vitro digestibility of oat straw and alfalfa stems. | five white rot basidiomycetes were evaluated for their potential to improve ruminal degradation of oat straw and alfalfa stems. phanerochaete chrysosporium (pc), scytinostroma galactinum (sg), phlebia tremellosa (pt), phellinus pini (pp), and pholiota mutabilis (pm) were incubated on oat straw and alfalfa stems for 30 d at 28 degrees c and 90% relative humidity. detergent fiber and total fiber components (neutral sugars, uronic acids, klason lignin [kl], and ester- and ether-linked non-core lign ... | 1992 | 1321801 |

| manganese(ii) oxidation by manganese peroxidase from the basidiomycete phanerochaete chrysosporium. kinetic mechanism and role of chelators. | manganese oxidation by manganese peroxidase (mnp) was investigated. stoichiometric, kinetic, and mnii binding studies demonstrated that mnp has a single manganese binding site near the heme, and two mniii equivalents are formed at the expense of one h2o2 equivalent. since each catalytic cycle step is irreversible, the data fit a peroxidase ping-pong mechanism rather than an ordered bi-bi ping-pong mechanism. mniii-organic acid complexes oxidize terminal phenolic substrates in a second-order reac ... | 1992 | 1429709 |
| multiple enzymatic pathways involved in the metabolism of glyceryl trinitrate in phanerochaete chrysosporium. | a study of glyceryl trinitrate metabolism by a filamentous fungus, phanerochaete chrysosporium, carried out with the 14c-labeled substrate, provides evidence for a multienzymatic system leading to di- and mononitrate derivatives. at least two independent enzymatic activities were detected in the cytosolic fraction: an aerobic glutathione s-transferase activity and an anaerobic nadph-dependent soluble cytochrome p450-like activity. other hemoproteins with enzymatic activities dependent upon the p ... | 1992 | 1326993 |
