PETase (PET-degrading enzyme, origin I. sakaiensis)

PETase is a poly(ethylene terehphthalate)-degrading enzyme first identified in Ideonella sakaiensis. BBa_K2010999 is the sequence for the E. coli K12 optimized DNA sequence for PETase. The catalytic activity of IsPETase can be characterized using a p-nitrophenol butyrate (pNPB) assay, in which PETase cleaves the ester bond of pNPB to release p-nitrophenolate. The absorbance of this compound can be measured at 405 nm to reflect IsPETase activity.
