    1.14.13.81 | malfunction |
a Chl27-antisense Arabidopsis mutant accumulates the cyclase substrate magnesium-protoporphyrin IX monomethyl ester and does not produce protochlorophyllide a |
700629 |
| 1.14.13.81 | malfunction |
a Rubrivivax gelatinosus strain with disrupted acsF gene cannot synthesize bacteriochlorophyll under oxygenated conditions but accumulates the substrate magnesium-protoporphyrin IX monomethyl ester, in contrast, under low-oxygene conditions the phenotype is similar to the wild-type, an alternative pathway for the reaction exists vie the bchE genes |
700629 |
| 1.14.13.81 | malfunction |
crd1 strains fail to accumulate photosystem 1 (PS 1) and light-harvesting complex 1 (LHC 1) during hypoxia or copper deficiency, and have reduced amounts of LHC 2, Crd1 abundance is increased in copper or oxygen deficient cells |
700629 |
| 1.14.13.81 | malfunction |
Cth1 accumulates in copper-sufficient, oxygenated cells |

| 1.14.13.81 | malfunction |
transgenic tobacco with antisense NTZIP-RNA displays chlorosis and a lack of the ability to turn green under normal growth conditions |
700629 |
| 1.14.13.81 | malfunction |
xantha-l35 and viridis-k deficient mutants grown in the dark, fed with delta-aminolevulinic acid, accumulate the substrate magnesium-protoporphyrin IX monomethyl ester and produce reduced amounts of protochlorophyllide a, in vitro complementation assay with mutants the aerobic cyclase is composed of at least 3 gene products, 1 soluble and 2 membrane-bound proteins (xantha-l and viridian-k) |
700629 |
| 1.14.13.81 | metabolism |
protochlorophyllide a production (formation of the isocyclic ring) via several intermediates in the chlorophyll biosynthesis pathway |
700629 |
| 1.14.13.81 | malfunction |
the Arabidopsis chl27-t knock-down mutant has a T-DNA insertion within the promoter region reducing mRNA levels dramatically, growth is slowed down and plants look pale due to chloroplast development defects (unstacking of thylakoid membranes), chlorophyll fluorescence analysis shows a low photosynthetic activity, numerous nuclear genes involved in pigment biosynthesis, photosynthesis (light-harvesting complex I and II, photo system I and II), for iron acquisition, carbon fixation, cold acclimation, and for electron carriers are repressed, stress and detoxifying related gene expression is affected most prominently, more than 600 genes are repressed, a similar number of genes are induced |
700711 |
| 1.14.13.81 | metabolism |
enzyme is involved in the protochlorophyllide a synthesis |
700711 |
| 1.14.13.81 | metabolism |
magnesium-protoporphyrin IX monomethylester cyclase is one of the key enzymes of the bacteriochlorophyll biosynthesis pathway |
