X-ray crystal structure of the light-independent protochlorophyllide reductase
Photosynthetic organisms adopt two different strategies for the reduction of the C17 = C18 double bond of protochlorophyllide (Pchlide) to form chlorophyllide a, the direct precursor of chlorophyll aExpand

A Second Nitrogenase-like Enzyme for Bacteriochlorophyll Biosynthesis
In most photosynthetic organisms, the chlorin ring structure of chlorophyll a is formed by the reduction of the porphyrin D-ring by the dark-operative nitrogenase-like enzyme, protochlorophyllideExpand

Identification of Two Homologous Genes, chlAI and chlAII, That Are Differentially Involved in Isocyclic Ring Formation of Chlorophyll a in the Cyanobacterium Synechocystis sp. PCC 6803*
The isocyclic ring (E-ring) is a common structural feature of chlorophylls. The E-ring is formed by two structurally unrelated Mg-protoporphyrin IX monomethylester (MPE) cyclase systems,Expand

An unexpectedly branched biosynthetic pathway for bacteriochlorophyll b capable of absorbing near-infrared light
Chlorophyllous pigments are essential for photosynthesis. Bacteriochlorophyll (BChl) b has the characteristic C8-ethylidene group and therefore is the sole naturally occurring pigment having anExpand

Metabolic engineering of the Chl d-dominated cyanobacterium Acaryochloris marina: production of a novel Chl species by the introduction of the chlorophyllide a oxygenase gene.
In oxygenic photosynthetic organisms, the properties of photosynthetic reaction systems primarily depend on the Chl species used. Acquisition of new Chl species with unique optical properties mayExpand

Completion of biosynthetic pathways for bacteriochlorophyll g in Heliobacterium modesticaldum: The C8-ethylidene group formation.
Heliobacteria have the simplest photosynthetic apparatus, i.e., a type-I reaction center lacking a peripheral light-harvesting complex. Bacteriochlorophyll (BChl) g molecules are bound to theExpand

Ubiquity and quantitative significance of detoxification catabolism of chlorophyll associated with protistan herbivory
Chlorophylls are essential components of the photosynthetic apparati that sustain all of the life forms that ultimately depend on solar energy. However, a drawback of the extraordinaryExpand

Significant enhancement in the power-conversion efficiency of chlorophyll co-sensitized solar cells by mimicking the principles of natural photosynthetic light-harvesting complexes.
Dye-sensitized solar cells (DSSCs) are similar to natural photosynthesis in the initial processes involving in light-harvesting and charge separation. In order to mimic those natural photosyntheticExpand

Non‐enzymatic conversion of chlorophyll‐a into chlorophyll‐d in vitro: A model oxidation pathway for chlorophyll‐d biosynthesis
Chlorophyll‐a (Chl‐a) was readily converted into Chl‐d under mild conditions without any enzymes. Treatment of Chl‐a dissolved in dry tetrahydrofuran (THF) with thiophenol and acetic acid at roomExpand

Dark-operative protochlorophyllide oxidoreductase generates substrate radicals by an iron-sulphur cluster in bacteriochlorophyll biosynthesis
Photosynthesis converts solar energy to chemical energy using chlorophylls (Chls). In a late stage of biosynthesis of Chls, dark-operative protochlorophyllide (Pchlide) oxidoreductase (DPOR), aExpand
