| Enzyme Function | FUNCTION: Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (Ref.1). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (Ref.1, PubMed:23592055). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (Ref.1, PubMed:23592055). Capable of degrading the bioplastic poly(lactic acid) (PLLA) (PubMed:28671263). {ECO:0000269|PubMed:23592055, ECO:0000269|PubMed:28671263, ECO:0000269|Ref.1}. |
