“…In Euglena gracilis, HgCl 2 inhibited synthesis of chlorophyll [10]. At sublethal concentrations mercury displaced the Mg 2+ ion of the tetrapyrrol ring, causing imbalances in protochlorophyll formation as well as affecting both chlorophyll synthesis and degradation [11].…”

Abstract:The effects of five organomercury compounds (methylmercuric chloride, phenylmercuric acetate, phenylmercuric borate, phenylmercuric citrate and diphenylmercury) on photosynthetic electron transport (PET) in spinach chloroplasts were investigated. The IC50 values of organomercury compounds related to PET inhibition in spinach chloroplasts varied in the range from 468 µmol dm -3 to 942 µmol dm -3 and were approximately by one order higher than the corresponding value determined for HgCl2 applied also in DMSO solution (IC50 = 58 µmol dm ). Due to extremely low aqueous solubility of diphenylmercury, the corresponding IC50 value could not be determined. Using EPR spectroscopy as probable sites of action of organomercury compounds in photosynthetic apparatus ferredoxin on the acceptor side of PS 1 and the quinone electron acceptors QA or QB on the reducing side of PS 2 were suggested.
