The gun4 gene is essential for cyanobacterial porphyrin metabolism.

FEBS letters - 30 Jul 2004

Wilde Annegret, Mikolajczyk Sandra, Alawady Ali, Lokstein Heiko, Grimm Bernhard

Abstract excerpt

Ycf53 is a hypothetical chloroplast open reading frame with similarity to the Arabidopsis nuclear gene GUN4. In plants, GUN4 is involved in tetrapyrrole biosynthesis. We demonstrate that one of the two Synechocystis sp. PCC 6803 ycf53 genes with similarity to GUN4 functions in chlorophyll (Chl) biosynthesis as well: cyanobacterial gun4 mutant cells exhibit lower Chl contents, accumulate protoporphyrin IX and show...
