Comamonas

Neopterin cyclic phosphate (92) has been isolated as an intermediate in the biosynthesis of pteridines from GTP in Comamonas Tracer studies show that the phosphoryl group in (92) originates from the... 

A taxonomic note there have been substantial developments in the taxonomy of pseudomonads, and many new genera have been proposed including, for example, Sphingomonas, Comamonas, and Variovorax, while denitrifying organisms described as pseudomonads have been referred to the general Thauera and Azoarcus (Anders et al. 1995).

The enzymes from Comamonas testosteroni for hydroxylation of quinoline to quinol-2-one (quinoline 2-oxidoreductase) and the dioxygenase responsible for the introduction of oxygen into the benzenoid ring (2-oxo-l,2-dihydroquinoline 5,6-dioxygenase) have been described (Schach et al. 1995). 

The transport of toluene-4-sulfonate into Comamonas testosteroni has been examined (Locher et al. 1993), and rapid uptake required growth of the cells with toluene-4-sulfonate or 4-methylbenzoate. From the results of experiments with various inhibitors, it was concluded that a toluenesulfonate anion/proton symport system operates rather than transport driven by a difference in electrical potential (A (/), and uptake could not take place under anaerobic conditions unless an electron acceptor such as nitrate was present.
