Asthma is a chronic inflammatory condition characterised by a variable degree of airflow limitation. Exacerbations during the course of asthma often occur due to environmental factors or infectious, mostly viral, aetiology. The present study reports the case of a 61-yr-old male with severe asthma hospitalised due to increasing respiratory distress. Since recovery was delayed despite anti-obstru...

Aromatic amine dehydrogenase was purified and characterized from Alcaligenes xylosoxidans IFO13495 grown on beta-phenylethylamine. The molecular mass of the enzyme was 95.5 kDa. The enzyme consisted of heterotetrameric subunits (alpha2beta2) with two different molecular masses of 42.3 kDa and 15.2 kDa. The N-terminal amino acid sequences of the alpha-subunit (42.3-kDa subunit) and the beta-subu...

Dissimilatory nitrite reductase was isolated from extracts of Alcaligenes xylosoxidans subsp. xylosoxidans (N.C.I.M.B. 11015), after activation of crude extracts by the addition of copper(II) sulphate. The enzyme was purified by a combination of (NH4)2SO4 fractionation and cationic-exchange chromatography to 93% homogeneity as judged by SDS/PAGE. SDS/PAGE and spray m.s. showed that the enzyme h...

Alcaligenes denitrificans NTB-1, previously isolated on 4-chlorobenzoate, also utilized 4-bromo-, 4-iodo-, and 2,4-dichlorobenzoate but not 4-fluorobenzoate as a sole carbon and energy source. During growth, stoichiometric amounts of halide were released. Experiments with whole cells and cell extracts revealed that 4-bromo- and 4-iodobenzoate were metabolized like 4-chlorobenzoate, involving an...

The membrane-bound hydrogenase of Alcaligenes eutrophus was solubilized from washed membranes of autotrophically grown cells. The enzyme consists of two types of subunits and is an iron-sulfur protein. A flavin compound was not detected. The enzyme reacts only with few artificial electron acceptors.
