Methods for enhancing a biological (e.g., catalytic) activity of a lipase, are provided. In some embodiments, the methods include the step of alkylating one or more cysteine residues present within the lipase. Also provided are modified polypeptides for which a biological activity is enhanced by the disclosed methods, methods for using the disclosed polypeptides, including for the transesterification of renewable oils to produce a biofuel, and cell free systems that include a lipase, to which one or more moieties, such as steroidal moieties, are conjugated. |
