10452902-10	1999	Gain of proteolytic activity of beta1/Pre3 and beta2/Pup1 was abolished or drastically reduced, respectively, if their respective propeptides were not N-terminally bound.	propeptides	130-141	proteasome core particle subunit beta 1	Saccharomyces cerevisiae S288C	38-42	
10500111-4	1999	The propeptides of beta6(Pre7) and beta7(Pre4) are intermediately processed to their final forms by beta2(Pup1) in the wild-type enzyme and by beta5(Pre2) and beta1(Pre3) in the beta2(Pup1) inactive mutants.	propeptides	4-15	proteasome core particle subunit beta 1	Saccharomyces cerevisiae S288C	165-169
