1.14.19.28 | metabolism |
desaturases, key enzymes in the metabolism of fatty acids, regulate the physical and biochemical properties of membranes. They adjust the composition of saturated and unsaturated fatty acids in response to changes in the environmental. This DELTA9-desaturation reaction normally requires molecular oxygen and reducing equivalents derived from NAD(P)H through an electron system consisting of either NADPH, cytochrome b5 and cytochrome b5-reductase in animals and fungi or ferredoxin-NADP+ oxidoreductase and ferredoxin in bacteria and plants |

1.14.19.28 | physiological function |
at optimum growth temperature, a decreased number of grana and thylakoids and an increased number of plastoglobules and their larger area are observed in desC-transgenic plants when compared to control plants. Transgenic plants respond to cold by reducing the chloroplast, granal and plastoglobule areas |

1.14.19.28 | physiological function |
the activity of antioxidant enzymes in the desC-transgenic plants depends on the operation of the introduced desC gene for acyl-lipid DELTA9-desaturase. Its activity results in an increase in the relative content of polyunsaturated fatty acids in the membrane lipids ensuring the liquid state of membranes during chilling. DesC-transgenic plants maintain a higher activity of antioxidant enzymes during 2 h incubation at 2°C. As a result, these plants resist more efficiently the accumulation of reactive oxygen species and reduce the rate of the lipid peroxidation |

1.14.19.28 | physiological function |
the D9-fatty acid desaturase initiates the synthesis of polyunsaturated fatty acids by introducing the first double bond at the C9 position of saturated fatty acid chains. These substrates can further be elongated by other classes of desaturase enzymes |

1.14.19.28 | physiological function |
the expression of acyl-lipid DELTA9-desaturase in tobacco plants results in the lower number of grana and thylakoids in a chloroplast in parallel with an increased number of plastoglobules and their larger area |
