Effects on the formation of antenna complex B870 of Rhodobacter capsulatus by exchange of charged amino acids in the N-terminal domain of the alpha and beta pigment-binding proteins.

Abstract excerpt

The N-terminal domains of the alpha and beta polypeptides of the B870 antenna complex of Rhodobacter capsulatus are oppositely charged. In both polypeptides two charged amino acids are located close to the N-terminus, and two of them are close to the hydrophobic central domain. To test the hypothesis that charged amino acids in the N-terminus have a function for insertion and assembly of pigment-binding...
