Cutinase Protein, Thermobifida Fusca (His)

The Cutinase protein assumes a pivotal role in cellular processes, catalyzing the hydrolysis of cutin, a key polyester comprising the plant cuticle structure. As documented in various studies, Cutinase exhibits esterase activity toward p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters), displaying a preference for short-chain substrates. Moreover, Cutinase demonstrates versatility by hydrolyzing triglycerides like triacetin, tributyrin, tricaprin, and trilaurin, with a pronounced affinity for short-chain substrates. Additionally, this enzyme displays the ability to hydrolyze the hemicellulose xylan and exhibits proficiency in degrading the widely used plastic poly(ethylene terephthalate) (PET). Furthermore, Cutinase can depolymerize poly(epsilon-caprolactone) (PCL), a synthetic aliphatic biodegradable polyester, highlighting its role in various biodegradation processes. The broad substrate specificity of Cutinase underscores its significance in enzymatic reactions involved in natural polymer breakdown and synthetic polymer degradation, showcasing its potential applications in environmental and industrial contexts.
