Model of the peptide splicing reaction inside the proteasome. Mechanism of production of the spliced the peptide RTKQLYPEW derived from gp100 (a) and the spliced peptide SLPRGTSTPK derived from SP110 (b). The balls represent the catalytic β-subunits of proteasomes with the hydroxyl group of the side chain of the N-terminal threonine
