Abstract
⺠We purified and characterised a 52.6 kDa PPO from Cleome gynandra leaves (CgPPO). ⺠CgPPO was optimally active and stable at pH 8.0/60 °C and pH 3.0 to 9.0/below 60 °C. ⺠CgPPO's diphenolase activity was higher than monophenolase and triphenolase activities. ⺠CgPPO showed a substrate specificity toward methylated and methoxylated substrates. ⺠CgPPO's activity was completely inhibited by Hg2+, strong reductants and thiols.
