    摘要: Disclosed herein are compositions and methods for delivering substrates for a depilatory product using an enzymatically-generated peracid. More specifically, a pH stabilized two component system is provided comprising (a) a first aqueous composition comprising hydrogen peroxide and at least one carboxylic acid ester substrate; wherein the pH of the first aqueous composition is 4.0 or less and (b) a second aqueous component comprising an enzyme catalyst having perhydrolytic activity and a buffer, wherein the pH of the second aqueous composition is at least 5.0; wherein the first and second aqueous compositions remain separated until use. The perhydrolytic enzyme catalyst may be in the form of a fusion protein comprising a perhydrolytic enzyme coupled through an optional peptide linker to a peptidic component having affinity for hair.

    摘要: An L-arabinose inducible expression system comprising a mutant arabinose promoter. This system exhibits an increase in heterologous protein production upon induction with L-arabinose and comprises a mutant araB promoter and an AraC transcription binding region. This system retains the tight regulatory control characteristic of the wild type arabinose operon.
