Figure 2. Effects of stable expression of the β5 proteasome subunit on chymotrypsin-like and peptidyl glutamyl-peptide hydrolase catalytic activities in LECs

Mean values of activity were calculated as percentage of activity compared to the control cells. Both proteasome chymotrypsin-like (CT-L) catalytic activity (157.34±6.03%) and proteasome peptidyl glutamyl-peptide hydrolase (PGPH) catalytic activity (132.00±17.11%) were significantly increased in PSMB5 transfected cells as compared with the control cells. Each column shows the average of three independent experiments (%). Similar results were obtained in the three independent cell lines analyzed.
