T cell receptor cross-reactivity expanded by dramatic peptide–MHC adaptability

T cell receptor cross-reactivity expanded by dramatic peptide–MHC adaptability, Published online: 17 September 2018; doi:10.1038/s41589-018-0130-4

Structural analysis shows that cross-reactivity of the T cell receptor DMF5 is governed by adaptability of the peptide antigen, which can undergo TCR-binding-induced frameshifting forcing the peptide C terminus to extend from the MHC-binding groove.

One mechanism of thalidomide teratogenicity involves binding to the CUL4–CRBN E3 ubiquitin ligase complex, which then mediates the degradation of transcription factors. New studies reveal that species-specific variants of the transcription factor SALL4 are differentially ubiquitinated and degraded via the thalidomide-bound complex.

Substrate-assisted enzymatic formation of lysinoalanine in duramycin, Published online: 03 September 2018; doi:10.1038/s41589-018-0122-4

During the biosynthesis of the lanthipeptide duramycin, DurN catalyzes stereospecific lysinoalanine formation by preorganizing the reactive conformation of the substrate, such that one of the substrate’s own residues serves as the catalytic base.
