10452902-4	1999	Activation of these subunits occurs during late assembly stages through intramolecular precursor autolysis removing propeptides attached to Thr1, which then serves as N-terminal nucleophile in substrate hydrolysis.	propeptides	116-127	homoserine kinase	Saccharomyces cerevisiae S288C	140-144	
10452902-12	1999	Thus, one role for the propeptides of active beta-type subunits might be to protect the mature subunits catalytic Thr1 alpha-amino group from acetylation.	propeptides	23-34	homoserine kinase	Saccharomyces cerevisiae S288C	114-118
