Spectral and catalytic properties of aryl-alcohol oxidase, a fungal flavoenzyme acting on polyunsaturated alcohols (2005)

Ferreira, P., Medina, M., Guillén, F., Martínez, M.J., Martínez, A.T.

Spectral and catalytic properties of the flavoenzyme AAO (aryl-alcohol oxidase) from Pleurotus eryngii were investigated using recombinant enzyme. Unlike most flavoprotein oxidases, AAO does not...

Prevalence of CagA and VacA Antibodies in Children with Helicobacter pylori-Associated Peptic Ulcer Compared to Prevalence in Pediatric Patients with Active or Nonactive Chronic Gastritis

Alarcón, T., Martínez, M. J., Urruzuno, P., Cilleruelo, M. L., Madruga, D., Sebastian, M., ...

VacA and CagA serological responses were detected in pediatric patients: 44 and 56%, respectively, in peptic ulcer (PU) patients, 33.3 and 44.4% in active chronic gastritis (ACG) patients, and 23.2...

Transformation of Industrial Dyes by Manganese Peroxidases from Bjerkandera adusta and Pleurotus eryngii in a Manganese-Independent Reaction

Heinfling, A., Martínez, M. J., Martínez, A. T., Bergbauer, M., Szewzyk, U.

We investigated the transformation of six industrial azo and phthalocyanine dyes by ligninolytic peroxidases from Bjerkandera adusta and other white rot fungi. The dyes were not oxidized or were...

Electron and Fluorescence Microscopy of Extracellular Glucan and Aryl-Alcohol Oxidase during Wheat-Straw Degradation by Pleurotus eryngii

Barrasa, J. M., Gutiérrez, A., Escaso, V., Guillén, F., Martínez, M. J., Martínez, A. T.

The ligninolytic fungus Pleurotus eryngii grown in liquid medium secreted extracellular polysaccharide (87% glucose) and the H2O2-producing enzyme aryl-alcohol oxidase (AAO). The production of both...

Laccase isoenzymes of Pleurotus eryngii: characterization, catalytic properties, and participation in activation of molecular oxygen and Mn2+ oxidation.

Muñoz, C, Guillén, F, Martínez, A T, Martínez, M J

Two laccase isoenzymes produced by Pleurotus eryngii were purified to electrophoretic homogeneity (42- and 43-fold) with an overall yield of 56.3%. Laccases I and II from this fungus are monomeric...

Anisaldehyde production and aryl-alcohol oxidase and dehydrogenase activities in ligninolytic fungi of the genus Pleurotus.

Gutiérrez, A, Caramelo, L, Prieto, A, Martínez, M J, Martínez, A T

A variety of simple aromatic compounds were identified in liquid cultures of the basidiomycetes Pleurotus cornucopiae, P. eryngii, P. floridanus, P. pulmonarius, P. ostreatus, and P. sajor-caju by...

Molecular cloning of aryl-alcohol oxidase from the fungus Pleurotus eryngii, an enzyme involved in lignin degradation.

Varela, E, Martínez, A T, Martínez, M J

Aryl-alcohol oxidase (AAO), an extracellular enzyme characteristic of fungi from the genus Pleurotus, constitutes a source for H2O2 required in lignin biodegradation. The gene aao has been cloned,...
