Abstract:
1. A thermostable mannose isomerase, which is generated from a bacterium belonging to the genus Agrobacterium , which thermostable mannose isomerase shows the following enzymatic properties: (a) function: converts D-mannose to D-fructose and vice versa; (b) substrate specificity: isomerizes the aldoses D-mannose and D-lyxose to their corresponding ketoses; however, does not function with D-glucose, D-galactose, L-mannose, D-xylose, L-xylose, D-arabinose, L-arabinose or D-ribose; (c) optimum pH: 7.5 to 8.5; (d) optimum temperature: continuously for two to three months at a temperature of 60° C.; and (e) stable pH: 6.0 to 10.0.
