Catalytic Activation of Esterases by PEGylation for Polyester Synthesis
Abstract In this work we explored PEGylation as an efficient strategy to improve esterase's catalytic performance. For this, we PEGylated three esterases, namely lipase from Candida antarctica B (CALB), lipase from Thermomyces lanuginosus (TL) and cutinase from Fusarium solani pisi (CUT) and ev...

The data revealed a higher polymerase activity for the lipase TL and cutinase PEGylated forms (88 % conversion for PEG‐lipase TL and 34 % for PEG‐cutinase). Molecular dynamics were used to evaluate the effect of PEG on the geometry of the active site of enzymes with lid domain (TL and CALB). These studies corroborate the experimental data revealing a more open active site cavity for the PEGylated catalysts facilitating the catalysis.
