Enzymatic formation of a conserved isoaspartate in ribosomal protein uS11

Isoaspartate (isoAsp) formation is typically viewed as a “molecular clock” through nonenzymatic degradation of aspartate or asparagine during protein aging. Here we report a nearly universal enzymatic pathway for the formation of a conserved isoAsp in the bacterial ribosomal protein uS11. Proteome-wide protein-protein...
