WebJul 18, 2016 · The final atomic model of the 26S human proteasome contained 28 subunits in the CP and six Rpt and 12 Rpn subunits in each RP, with 13,856 amino acids … WebThe 26S proteasome is a giant protease assembled from at least 32 different canonical subunits. In eukaryotic cells it is responsible for the regulated degradation of proteins marked for destruction by polyubiquitin tags. Mainly because of the conformational heterogeneity of the 26S holocomplex, its structure determination has been challenging. champion jogger set infant
