Ubiquitin occupancy, non-ubiquitin occupied and total protein ratios were generated for all partially ubiquitinated peptides detected in MG132 and DMSO control treated samples. a Relative ubiquitinated, non-ubiquitinated and protein ratios for all partially ubiquitinated peptides in the MG132 treated vs. native state. b Percent ubiquitin occupancy for partially ubiquitinated peptides in the MG132 treated and native conditions. c Relative ubiquitinated, non-ubiquitinated and protein ratios for all partially ubiquitinated peptides in the DMSO treated vs. native state. d Percent ubiquitin occupancy for partially ubiquitinated peptides in the DMSO treated and native conditions
