Abstract excerpt

We have examined mutants in the core light-harvesting complex of Rhodobacter sphaeroides in which the tryptophan residues located at positions alpha+11, beta+6, and beta+9 have been mutated to each of the three other aromatic amino acids, namely tyrosine, phenylalanine, and histidine. We confirm...
