1.3.7.7 | malfunction |
a strain lacking DPOR contains about 25% of the wild-type level of photosystems PSII and PSI when cultivated under light-activated heterotrophic growth conditions. Deletion of the chlL gene abolishes activity of the DPOR enzyme. Absence of the chlL gene causes a further 20% decrease in Chl content and therefore the resulting (pCER:por)/Dpor/DchlL strain termed SynPORreg reaches only 60-70% of Chl content present in wild-type |

1.3.7.7 | metabolism |
chlorophyll biosynthesis is catalyzed by two multi subunit enzymes; a light-dependent and a light-independent protochlorophyllide oxidoreductase |

1.3.7.7 | metabolism |
protochlorophyllide reduction is a key regulatory step in Chl biosynthesis |

1.3.7.7 | metabolism |
the three-subunit enzyme dubbed DPOR operates in the synthesis of Bchls a, b, and g |
726526 |
1.3.7.7 | metabolism |
two independent enzymes catalyze the reduction of protochlorophyllide to chlorophyllide, which is the penultimate step in chlorophyll biosynthesis. One is light-dependent NADPH:protochlorophyllide oxidoreductase and the second type is dark-operative protochlorophyllide oxidoreductase |
