additional information Synechocystis sp. PCC 6803 cyanobacterial 3,8-divinyl chlorophyllide reductase (DVR) is a Chl biosynthetic enzyme that has many promiscuous activities besides the 3,8-divinyl chlorophyllide reductase activity, e.g. 7-hydroxymethyl chlorophyll a reductase activity. The Chl c2 to Chl c1 conversion is existent in cyanobacteria as a promiscuous activity of F-DVR. Chl c1 is synthesized by the reduction of the 8-vinyl group of Chl c2 or Chl c1 is synthesized from monovinyl-protochlorophyllide by the dehydrogenase ?

additional information substrate specificity, overview. Cyanobacterial F-DVR exhibits a broad substrate specificity and converts 3,8-divinylprotochlorophyllide a, 3,8-divinyl chlorophyllide a, and 3,8-divinyl chlorophyll a to the respective monovinyl molecules. When 7-hydroxymethyl chlorophyllide (HMChlide) a is incubated with F-DVR, chlorophyllide a is generated Synechocystis sp. PCC 6803 ?

General Information

General Information Comment Organism
evolution either F-DVR or N-DVR is found in most photosynthetic organisms, yet both F-DVR and N-DVR exist in the genome of diatoms that contain Chl a and Chl c1 Synechocystis sp. PCC 6803
metabolism the enzyme is involved the chlorophyll biosynthetic pathways of oxygenic photosynthetic organisms. At the later steps of chlorophyll biosynthesis, 3,8-divinyl-chlorophyllide (Chlide) a is converted to monovinyl (MV)-Chlide a by DVR. Involvement of DVR in Chl c biosynthesis Synechocystis sp.
