Maleate cis-trans-isomerase activity of alcaligenes xylosoxidans subsp. xylosoxidans 260 [link]Paper  abstract   bibtex   
Alcaligenes xylosoxidans subsp. xylosoxidans 260 KM MGU was able to utilize maleic acid with the accumulation of L-malic, acetic, and propionic acids in the culture liquid. Maleic acid was found to enter the tricarboxylic acid cycle at the level of fumaric acid under the action of the membrane-bound maleate cisfrans-isomerase (EC 5.2.1.1). A. xylosoxidans was able to transform maleic acid throughout the entire cultivation period; however, the specific rate of maleic acid consumption peaked by the onset of the stationary phase, since the transformation of maleic acid was inhibited as a result of the accumulation and utilization of its transformation product, i.e., malate. The presence of intermediates of the tricarboxylic acid cycle, such as α-ketoglutarate or citrate, in growth medium as the second carbon sources delayed the transformation of maleic acid, probably, due to competitive inhibition. Maleic acid completely inhibited catabolism of sugars (glucose, xylose, fructose). The maleate isomerase activity of intact cells, toluene-permeabilized cells, and cell-free extract peaked at +40°C and pH 7.6.
