Effect of aromatic molecules on the aggregation of C-phycocyanin. Quantum chemical calculations on phycocyanobilin and phycoerythrobilin. 1975

M Kumbar, and R MacColl

The energies of the highest occupied and lowest empty molecular orbitals were calculated for the chromophore groups of the proteins phycocyanin and phycoerythrin. These tetrapyrrole groups on the algal proteins are shown to provide them with the potential of ating as efficient electron donors and acceptors. In addition, the pi electron charges and bond orders were also computed.
