They suggested that ammonia may adversely affect the developing embryo by decreasing the concentration of a-ketoglutarate by converting it to glutamate, thereby reducing the flux through the tricarboxylic acid cycle (TCA) cycle and depleting ATP in embryonic cells and reducing the availability of ATP for embryonic cells during a stage of development.
At 20C, exogenous CaCl2 alleviated the negative effects of temperature stress on the total respiration rate by enhancing the activity of tricarboxylic acid cycle (TCA).
Moreover, PSII isnt the only component that is lacking in this genome: RuBisCo (ribulose-1,5 bisphosphate carboxylase-oxygenase that fixes CO2) and the tricarboxylic acid cycle (TCA) that usually are present in the cyanobacteria, are missing in UCYN-A.
