Properties of L-lactate oxidase from Aerococcus viridans are described. The gene encoding the enzyme has been isolated. From its cDNA sequence the amino acid sequence has been derived and shown to have high similarity with those of other enzymes catalyzing oxidation of L-alpha-hydroxy acids, including flavocytochrome b2, lactate monooxygenase, glycolate(More)
This paper is the fifth in a series dealing with reference procedures for the measurement of catalytic activity concentrations of enzymes at 37 degrees C and the certification of reference preparations.

One of the characteristic complaints of patients with chronic fatigue syndrome (CFS) is the skeletal muscle-related symptom. However, the abnormalities in the skeletal muscle that explain the symptom are not clear. Herein, we show that our patients with CFS had a deficiency of serum acylcarnitine. As carnitine has an important role in energy production and(More)

Choline oxidase was purified from the cells of Arthrobacter globiformis by fractionations with acetone and ammonium sulfate, and column chromatographies on DEAE-cellulose and on Sephadex G-200. The purified enzyme preparation appeared homogeneous on disc gel electrophoresis. The enzyme was a flavoprotein having a molecular weight of approx. 83,000 (gel(More)
The native flavin, FMN, has been removed from the l-lactate oxidase of Aerococcus viridans, and the apoprotein reconstituted with 12 FMN derivatives with various substituents at the flavin 6- and 8-positions. Impressive linear relationships are exhibited between the sum of the Hammett final sigma(para) and final sigma(ortho) parameters and the redox(More)
The early diagnostic efficacy of serial Candida antigen detection by the assay kit CAND-TEC (a latex particle agglutination test) was evaluated in 12 episodes in 10 patients with acute leukemia after post-remission chemotherapy. To determine the timing to initiate antifungal chemotherapy, we performed the CAND-TEC assay serially in each patient. When the(More)
