| chlorophyllide a 31-hydratase | The enzyme, together with EC 1.3.7.15, chlorophyllide-a reductase, and EC 1.1.1.396, bacteriochlorophyllide-a dehydrogenase, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a. The enzymes can act in multiple orders, resulting in the formation of different intermediates, but the final product of the cumulative action of the three enzymes is always bacteriochlorophyllide a. The enzyme catalyses the hydration of a vinyl group on ring A, converting it to a hydroxyethyl group. Group: Enzymes. Synonyms: bchF (gene name). Enzyme Commission Number: EC 4.2.1.165. 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-5006; chlorophyllide a 31-hydratase; EC 4.2.1.165; bchF (gene name). Cat No: EXWM-5006. |  |
| chlorophyllide a hydrolase | This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green filamentous bacteria (Chloroflexaceae), catalyses the first committed step in the biosynthesis of bacteriochlorophylls c, d and e, the removal of the C-132-methylcarboxyl group from chlorophyllide a. The reaction is very similar to the conversion of pheophorbide a to pyropheophorbide a during chlorophyll a degradation, which is catalysed by EC 3.1.1.82, pheophorbidase. Group: Enzymes. Synonyms: bciC (gene name). Enzyme Commission Number: EC 3.1.1.100. 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.

| chlorophyllide-a oxygenase | Chlorophyll b is required for the assembly of stable light-harvesting complexes (LHCs) in the chloroplast of green algae, cyanobacteria and plants. Contains a mononuclear iron centre. The enzyme catalyses two successive hydroxylations at the 7-methyl group of chlorophyllide a. The second step yields the aldehyde hydrate, which loses H2O spontaneously to form chlorophyllide b. Chlorophyll a and protochlorophyllide a are not substrates. Group: Enzymes. Synonyms: chlorophyllide a oxygenase; chlorophyll-b synthase; CAO. Enzyme Commission Number: EC 1.14.13.122. CAS No. 216503-73-0. 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-0723; chlorophyllide-a oxygenase; EC 1.14.13.122; 216503-73-0; chlorophyllide a oxygenase; chlorophyll-b synthase; CAO. Cat No: EXWM-0723. | |
| chlorophyllide a reductase | The enzyme, together with EC 1.1.1.396, bacteriochlorophyllide-a dehydrogenase, and EC 4.2.1.165, chlorophyllide-a 31-hydratase, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a. These enzymes can act in multiple orders, resulting in the formation of different intermediates, but the final product of the cumulative action of the three enzymes is always bacteriochlorophyllide a. This enzyme catalyses a trans-reduction of the B-ring; the product has the (7R,8R)-configuration. In addition, the enzyme has a latent activity of EC 1.3.7.13, 3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin). The enzyme contains a [4Fe-4S] cluster, and structurally resembles the Fe protein/MoFe protein complex of nitrogenase (EC 1.18.6.1), which catalyses an ATP-driven reduction. Group: Enzymes. Synonyms: bchX (gene name); bchY (gene name); bchZ (gene name); COR. Enzyme Commission Number: EC 1.3.7.15. Storage: Store it at +4 ?C for short term.

| 3,8-divinyl chlorophyllide a reductase | The enzyme, found only in bacteriochlorophyll b-producing bacteria, catalyses the introduction of a C-8 ethylidene group. The enzyme contains a [4Fe-4S] cluster, and structurally resembles the Fe protein/MoFe protein complex of nitrogenase. It is very similar to EC 1.3.7.15, chlorophyllide a reductase, and is composed of three subunits. Two of them form the catalytic component, while the third one functions as an ATP-dependent reductase component that catalyses the electron transfer from ferredoxin to the catalytic component. Group: Enzymes. Enzyme Commission Number: EC 1.3.7.14. 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.

| 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. | |
