Humicola insolens cutinase with N-terminal His-Tag

The Humicola insolens cutinase (HIC) (EC 3.1.1.74, cutinase) belongs to the serine-α -β-hydrolase family (Nielsen et al., 2005) and can be used to degrade polymers like polyethylene terephthalate (Espino-Rammer et al., 2013). The catalytic pocket consists of the triad of a serine, histidine and aspartic acid (Kold et al., 2014). In addition it was reported that HIC catalyze condensation and lactone ring-opening polymerizations in an organic phase (Hunsen et al., 2008) at an optimal activity of 70°C. Assays showed no ester cleavage activity after incubating at 70°C for 15 min. An N-terminal attached Polyhistag enables purification via immobilized metal affinity chromatography (IMAC). Experimental results are available in the inducing operon of HIC.
