Abstract
The photoreceptor complexes of Rhodobacter sphaeroides and Rhodobacter capsulatus have many features in common Their reaction centers have about 80 homology between the amino acid sequences of their respective L M and H polypeptides 1 The electrochemical and spectroscopic details for the primary photochemical events are nearly identical 2 Both have a core lightharvesting LH complex with a Qy band near 875 nm and an accessory LH complex B800–850 whose amount varies inversely with the light intensity used for growing the bacteria
