Activation of isomerization

A true xylose isomerase, that did not require arsenate for its activity, was found in strains of Lactobacillus, especially L. brevis (25). In this study, it was found that the activity of isomerization of glucose and xylose were essentialfy equal, and that ribose was isomerized to ribulose at a reduced rate 24). The xylose isomerases from this strain, like those from other species, requires divalent cations for activity. In this case, Mn and Co were found to be required for activity. In other studies, Co has been found to increase xylose isomerase stability 25,26,21. ... [Pg.487]

Metals differ in their ability to catalyze isomerization. Both the relative rate of transformation of the individual isomers and the initial isomer distribution vary with the metal. The order of decreasing activity of platinum metals in catalyzing the isomerization of alkenes was found to be Pd >- Rh, Ru, Pt > Os > Ir.53 Platinum is generally the preferable catalyst if isomerization is to be avoided. The most active Raney nickel preparations rival palladium in their activity of isomerization. [Pg.622]
