Characterization of extracellular substrate specific glucose and xylose isomerases of Chainia

Specific glucose and xylose isomerases have been identified in cell-free culture filtrates of a Chainia species. Treatment with DEAE-cellulose selectively adsorbed xylose isomerase activity while only the glucose isomerase was adsorbed on CM-cellulose. Glucose isomerase was completely inhibited by x...

Description
Summary:Specific glucose and xylose isomerases have been identified in cell-free culture filtrates of a Chainia species. Treatment with DEAE-cellulose selectively adsorbed xylose isomerase activity while only the glucose isomerase was adsorbed on CM-cellulose. Glucose isomerase was completely inhibited by xylose at 1.3 x 10 super(-4) M concentration. The differential identity of the extracellular glucose and xylose isomerases, unique to Chainia , is discussed.
