additional information | construction of a mutants lacking chlAI, chlAII, slr0905, sll1242, or slr0309, respectively, the DELTAchlAI mutant fails to grow under aerobic conditions with anomalous accumulation of a pigment with fluorescence emission peak at 595 nm, the growth defect is restored by the cultivation under oxygen-limited micro-oxic conditions. MPE accumulation is also detected in DELTAchlAII mutant grown under microoxic conditions, but not in any of the bchE mutants. The phenotype is consistent with the expression pattern of two chlA genes: chlAII was induced under micro-oxic conditions in contrast to the constitutive expression of chlAI, phenotypes, overview | Synechocystis sp.

additional information | AcsF and BchE perform incorporation of an oxygen atom from molecular oxygen and water into the C-13 position of Mg-protoporphyrin IX monomethylester, respectively. ChlAI is the sole MPE cyclase system under aerobic conditions and the induced ChlAII operates together with ChlAI under micro-oxic conditions | Synechocystis sp. PCC 6803 | ? | - |
