Function
PETH2_THEFU Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:23604968, PubMed:24728714, PubMed:31690819, Ref.4). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:15638529, PubMed:23604968, PubMed:24728714, PubMed:25545638, PubMed:31690819, Ref.4). Also hydrolyzes the triglycerides triacetin, tributyrin, tricaprin, and trilaurin, with a preference for short-chain substrates (PubMed:15638529). Hydrolyzes the hemicellulose xylan (PubMed:20816933). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (PubMed:25545638, PubMed:31690819, PubMed:32269349, Ref.4). Can also depolymerize poly(epsilon-caprolactone) (PCL), a synthetic aliphatic biodegradable polyester (PubMed:15638529). Hydrolyzes polyoxyethylenesorbate esters with a preference for shorter chain lengths (PubMed:20816933).[1] [2] [3] [4] [5] [6] [7] [8]
