Effective charge saturation in ferritin cages.

Abstract excerpt

Ferritins are proteins consisting of 24 subunits that make a spherical cage structure. We prepared a series of net-charge mutants of Escherichia coli and Pseudo-nitzschia multiseries ferritins (EcFtn and PmFtn, respectively) in which glutamate (Glu) and aspartate (Asp) residues located at the outer surface of the cage were substituted with glutamine and asparagine or vice versa. The effective negative charges of...
