An Electron Transport System in Maize Roots for Reactions of Glutamate Synthase and Nitrite Reductase

“…A Cyt c reduction assay which is dependent on the presence of NADPH as a primary electron donor, a pyridine nucleotide reductase, an electron carrier, and Cyt c as an electron acceptor, has also been used to characterize Fd or Fd-like proteins as an electron carrier (1,4,11,23). Using the Cyt c reduction assay system, a non-heme iron containing protein which transfers electrons from either NADPH or NADH to Cyt c has been identified in extracts prepared from young maize roots.…”

Dynamic photosynthesis under a fluctuating environment: a modelling-based analysis

“…For the same species, and using antibodies to measure Fd, Böhme (1977) reported 475 Chl/Fd (2 Fd/P700) and Bohme (1978) reported a ratio of 250 Chl/Fd (3 Fd/PSI). However, Matson and Kimura (1975) reported a ratio of only 33 Chl/Fd in S. oleracea and 11 Chl/Fd in Petroselinum crispum, also using antibodies to measure Fd. It is unclear why the experiment by Matson and Kimura (1975) resulted in an order of magnitude difference with respect to the other experiments.…”

It is unclear why the experiment by Matson and Kimura (1975) resulted in an order of magnitude difference with respect to the other experiments. Assuming 2 Fd/P700 (which would result in 222 Chl/Fd with our parameter set), this leads to an Fd content of 1.28×10 −6 mol m −2 .…”
