Metabolite channeling by a dynamic metabolon: The specialized metabolite dhurrin breaks down into cyanide when plant cell walls have been chewed, deterring insect pests. Laursen et al. found that the enzymes that synthesize dhurrin in sorghum assemble as a metabolon in lipid membranes (see the Perspective by Dsatmaichi and Facchini). The dynamic nature of metabolon assembly and disassembly provides dhurrin on an as-needed basis. Membrane-anchored cytochrome P450s cooperated with a soluble glucosyltransferase to channel intermediates toward efficient dhurrin production. Science , this issue p. 890 ; see also p. 829

Biohybrid amphiphiles have been prepared from terminal azide functionalised polystyrene and an alkyne functionalised peptide or protein via a Cu(I) catalysed Huisgen [3 + 2] dipolar cycloaddition reaction.
