Popis: Caralluma umbellata peroxidase (CUP) is an acidic heme-containing protein having a molecular weight of ~42 kDa and is specific to guaiacol. It is not a glycoprotein. It was purified to 12.5-fold purity with 6.16 % yield. Its activity is dependent on hydrogen peroxide and has an optimum pH and temperature of 6.2 and 45 °C respectively. It can decolorize dyes, viz., Aniline Blue, Reactive Black 5, and Reactive Blue 19 but not Congo Red, while HRP can decolorize Congo Red also. It has lignin-degrading potentiality as it can decompose veratryl alcohol. Detoxification of phenol was more by CUP compared to HRP while with p-nitrophenol HRP has a greater detoxification rate. Based on our results, CUP was identified to be capable of oxidizing a variety of hazardous substances and also a lignin-degrading plant biocatalyst.
