RESUMO

Acidic nondenaturing PAGE revealed inhomogeneity of the MASP-1 catalytic region caused by deamidation as the reason behind previous unsuccessful crystallization attempts. Monitoring the separation of the various species by acidic nondenaturing PAGE during purification helped to obtain pure protein, which was subsequently crystallized.
