Notes from publications   A curated excerpt with information about the mutation from the publications found above	To identify the physiological dimeric interface Scietti et al. introduced the Arg714Asn mutation in the PLOD3 recombinant protein. As verified by SDS-PAGE and enzymatic deglycosylation experiments this mutation added a novel glycosylation site at Asn714, in the middle of the tal-to-tail dimerization interface. This caused enzyme monomerization identifying the c-terminal interface as the physiological one.
