additional information | deltaH324 mutant, mutated hemH gene, contains a truncated FeCH enzyme lacking the C-terminal domain, is localized to the membrane fraction, C-terminal domain is not necessary for membrane association of the enzyme, mutant grows poorly, has dramatically FeCH reduced activity, resulting in highly upregulated 5-aminolevulinic acid synthesis, suffers strongly from photooxidative stress as a consequence of disturbed tetrapyrrole biosynthesis and accumulation of phototoxic intermediates of this pathway. C1.8 mutant strain, carries a short deletion in Chl-binding CP47 protein, grows very slowly, complementation with the mutated hemH gene from mutant deltaH324 | Synechocystis sp. PCC 6803 |
