additional information
-
 thiolase B exhibits cold-lability: loss of acitvity is more pronounced at 4°C than at 30°C, in the presence of KCl, thiolase A is stable under the same conditions, thiolase A exhibits higher stabiliy than thiolase B at 46°C, lability of the thiolase B might be compensated for by the formation of a more stable multienzyme complex Rattus norvegicus
