Notes from publications   A curated excerpt with information about the mutation from the publications found above	Heikkinen et al. performed site-directed mutagenesis to characterize PLOD3 biochemical properties. The Asp669Ala mutation decreased lysyl-hydroxylase activity dramatically, whereas it had no effect on the glycosyltranferase activity. Scietti et al. described this residue to be involved in Fe2+ coordination in the catalytic site.
