    3.1.1.14 | evolution |
IbChlase in TN57, CN1927, and CYY8467 shares 95% identity, and an eight-nucleotide sequence of Chlase in CYY8467 is missing due to a frame-shift mutation of the Chlase gene leading to early termination of gene translation. Sequences from cutlivars TN57 and CN1927 are clustered together in a clade as Chlase2. Phylogenetic analysis and tree |

the deduced amino acid sequence of recombinant CyanoCLH comprises a unique lipase-motif GHSLG, which differs from the GHSRG sequence of other plants and lacks a histidine of the typical and conserved catalytic triad Ser-Asp-His |

chlorophyll breakdown is indistinguishable between wild-type plants and clh1 and clh1/clh2 mutant plants. By contrast, chlorophyll degradation is significantly delayed in an Arabidopsis thaliana mutant that lacks pheophytinase (PPH), catalyzing the breakdown of phytol and known to be associated with chlorophyll catabolism. These data indicate that PPH, not CLH1, is responsible for the majority of MeJA-enhanced chlorophyll breakdown, even though CLH1 is highly induced by methyl jasmonate |

exposure to phenanthrene, a model compound for polycyclic aromatic hydrocarbon (PAH) stress, leads to enhancement of both chlorophyll synthesis and degradation, but the degradation rate is faster. Phenanthrene accumulation has significant and positive effects on increase of glutamate, 5-aminolevulinic acid, uroporphyrinogen III, protoporphyrin IX, Mg-protoporphyrin IX and protochlorophyllide concentrations. Over the exposure time, wheat leaf color turns light. With the accumulation of phenanthrene, the concentrations of glutamate, 5-aminolevulinic acid, uroporphyrinogen III, protoporphyrin IX, Mg-protoporphyrin IX and protochlorophyllide increase while the concentrations of porphobilinogen and Chlorophyll b decrease. Also chlorophyll a content rises initially and then declines. Uroporphyrinogen III synthase and chlorophyllase are activated and porphobilinogen deaminase activity declines in the treatments. There is a negative correlation between phenanthrene accumulation and total chlorophyll. Toxicity of PAHs to plants and crop PAH-adaptive mechanism in the environment, overview. With increasing phenanthrene accumulation in wheat leaves, the growth of wheat leaves is inhibited, and mature wheat leaf color turns light |

the incomplete Chlase2 protein of cultivar CYY8467 lacks for the core domain, suggesting that the incomplete CYY8467 Chlase2 does not function in Chl degradation |

the enzyme is involved in the chlorophyll metabolism. Chlorophyllide is not a first intermediate of chlorophyll breakdown, almost unchanged chlorophyll to chlorophyllide ratio after 24 h of paraquat treatment. Melatonin treatment of seeds enhances the ability of pea seedlings to accelerate chlorophyll breakdown and chlorophyll de novo synthesis before oxidative stress exerted by herbicide paraquat treatment appears and several hours after stressing, respectively, while during prolonged paraquat incubation, melatonin delays chlorophyll degradation |
