| Chlorophyll a | Chlorophyll a is a photosynthetic pigment required by eukaryotes and cyanobacteria for photosynthesis. It is the main donor of electron transport chain, and it is a dye and metabolite. Synonyms: Magnesium chlorophyll; Chlorophyll A; Chlorophyll-1; Magnesium Pheophytin; Vegetable Chlorophyll; α-Chlorophyll; (SP-4-2)-[(2E,7R,11R)-3,7,11,15-tetramethyl-2-hexadecenyl (3S, 4S, 21R)-9-ethenyl-14-ethyl-21-(methoxycarbonyl)-4, 8, 13, 18-tetramethyl-20-oxo-3-phorbinepropanoato(2-)-κN23, κN24, κN25, κN26]-Magnesium; Chlorophyll a, from spinach. Grades: 98%. CAS No. 479-61-8. Molecular formula: C55H72MgN4O5. Mole weight: 893.49. | |
| chlorophyllase | Chlorophyllase has been found in higher plants, diatoms, and in the green algae Chlorella. This enzyme forms part of the chlorophyll degradation pathway and is thought to take part in de-greening processes such as fruit ripening, leaf senescence and flowering, as well as in the turnover and homeostasis of chlorophyll. This enzyme acts preferentially on chlorophyll a but will also accept chlorophyll b and pheophytins as substrates. Ethylene and methyl jasmonate, which are known to accelerate senescence in many species, can enhance the activity of the hormone-inducible form of this enzyme. Group: Enzymes. Synonyms: CLH; Chlase. Enzyme Commission Number: EC 3.1.1.14. CAS No. 9025-96-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-3441; chlorophyllase; EC 3.1.1.14; 9025-96-1; CLH; Chlase. Cat No: EXWM-3441. |  |
| geranylgeranyl-bacteriochlorophyllide a reductase | The enzyme catalyses the successive reduction of the geranylgeraniol esterifying group to phytol, reducing three out of four double bonds, and transforming geranylgeranyl bacteriochlorophyllide a via dihydrogeranylgeranyl bacteriochlorophyllide a and tetrahydrogeranylgeranyl bacteriochlorophyllide a to bacteriochlorophyll a. The enzyme can also accept the pheophytin derivative geranylgeranyl bacteriopheophytin, converting it to bacteriopheophytin a. Group: Enzymes. Synonyms: geranylgeranyl-bacteriopheophytin reductase; bchP (gene name). Enzyme Commission Number: EC 1.3.1.111. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-1284; geranylgeranyl-bacteriochlorophyllide a reductase; EC 1.3.1.111; geranylgeranyl-bacteriopheophytin reductase; bchP (gene name). Cat No: EXWM-1284. | |
| pheophorbidase | This enzyme forms part of the chlorophyll degradation pathway, and is found in higher plants and in algae. In higher plants it participates in de-greening processes such as fruit ripening, leaf senescence, and flowering. The enzyme exists in two forms: type 1 is induced by senescence whereas type 2 is constitutively expressed. The enzyme is highly specific for pheophorbide as substrate (with a preference for pheophorbide a over pheophorbide b) as other chlorophyll derivatives such as protochlorophyllide a, pheophytin a and c, chlorophyll a and b, and chlorophyllide a cannot act as substrates. Another enzyme, called pheophorbide demethoxycarbonylase (PDC),produces pyropheophorbide a from pheophorbide a without forming an intermediate although the precise reaction is not yet known. Group: Enzymes. Synonyms: phedase; PPD. Enzyme Commission Number: EC 3.1.1.82. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-3511; pheophorbidase; EC 3.1.1.82; phedase; PPD. Cat No: EXWM-3511. | |
| photosystem II | Contains chlorophyll a, β-carotene, pheophytin, plastoquinone, a Mn4Ca cluster, heme and non-heme iron. Four successive photoreactions, resulting in a storage of four positive charges, are required to oxidize two water molecules to one oxygen molecule. Group: Enzymes. Enzyme Commission Number: EC 1.10.3.9. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0487; photosystem II; EC 1.10.3.9. Cat No: EXWM-0487. | |
