Method "Researchers investigated the organisation of the photosynthetic apparatus in Phaeospirillum molischianum, using biochemical fractionation and functional kinetic measurements."
Comments "From the one electron per centre calibration of TMPD [N,N,N',N'-tetramethyl-p-phenylenediamine] oxidation using a single turnover flash, researchers can estimate the quinone corresponding to the fast phase as about 25 quinones (50 electrons) per RC."
