Artificial enzymes {utilizing|using} the genetically encoded non-proteinogenic amino acid p-aminophenylalanine (pAF) as catalytic residue are {able to|in a position to} react with carbonyl compounds {through|via|by means of|by way of} an iminium ion mechanism, {making|creating|producing|generating} reactions {possible|feasible|achievable|attainable|doable|probable} {that have|which have} no equivalent in nature. {Here|Right here}, we report an in vivo biocatalytic cascade {that is|that’s|which is|that is certainly|that is definitely|that may be} augmented with such an artificial enzyme catalyzed new-to-nature reaction. The artificial enzyme {in this|within this} study {is a|is really a|is actually a|can be a|is often a|is usually a} pAF containing evolved variant {of the|from the|in the|on the|with the|of your} Lactococcal multidrug resistance Regulator, designated LmrR_V15pAF_RMH, which {efficiently|effectively} converts in vivo {produced|created|made|developed} benzaldehyde derivatives {into the|in to the} corresponding hydrazone {products|goods|items|merchandise|solutions} inside E. coli cells.
