Catalyzed Reactions

Two GaCl3-catalyzed reactions, which utilize isocyanides as a one-carbon unit, are described: a [4+1] cycloaddition of α,β-unsaturated carbonyl compounds with isocyanides, and an insertion reaction of isocyanides into a C-O bond of ketals and acetals. The relatively low affinity of GaCl3 toward heteroatoms enables the successful catalysis.

Artificial enzymes utilizing the genetically encoded non-proteinogenic amino acid p-aminophenylalanine (pAF) as catalytic residue are able to react with carbonyl compounds through an iminium ion mechanism, making reactions possible that have no equivalent in nature. Here, we report an in vivo biocatalytic cascade that is augmented with such an artificial enzyme catalyzed new-to-nature reaction. The artificial enzyme in this study is a pAF containing evolved variant of the Lactococcal multidrug resistance Regulator, designated LmrR_V15pAF_RMH, which efficiently converts in vivo produced benzaldehyde derivatives into the corresponding hydrazone products inside E. coli cells. These in vivo biocatalytic cascades comprising an artificial enzyme catalyzed reactions are an important step towards achieving a hybrid metabolism.
