9-cis-Retinal

Description

In vivo, 9-cis-retinal is formed through oxidation of 9-cis-retinol by cis-retinol dehydrogenase (cRDH). (PMID:15572038 ). The generation of retinoic acid from retinol is a two-step reaction, with the rate-limiting step being the oxidation of retinol into the intermediate retinaldehyde. Two classes of. unrelated enzymes have been implicated in the oxidation of retinol, the classical cytosolic medium chain alcohol dehydrogenases and recently identified microsomal members of the short chain alcohol dehydrogenase reductase (SDR) superfamily. Further oxidation of the retinaldehyde to the retinoic acid is believed to be catalyzed by several cytosolic aldehyde dehydrogenases. Retinoids are micronutrients required to maintain and promote health of vertebrates. They act physiologically by participating in the visual cycle, in regulating cell differentiation, in embryonic development (PMID:10893430 ), in maintaining normal reproduction, and in the immune response (PMID:8882153 ). In non-ocular tissues, the effects of retinoids within the body are mediated through retinoic acid receptors (RARs) and retinoid X receptors (RXRs), which act to regulate gene expression as ligand-dependent transcription factors. The naturally occurring ligands for these nuclear receptors are thought to be all-trans-retinoic acid for RARs and 9-cis-retinoic acid for RXRs (PMID:10322133 ). While many details of the molecular actions of the RARs and RXRs in regulating gene transcription are understood (PMID:10418975 ), tissue-specific synthetic pathway(s) of their ligands has not been adequately defined. Nevertheless, the therapeutic efficacy of retinoids, including 9-cis-retinoic acid, is well established in both tissue culture and animal models of breast cancer (PMID:8825126 , PMID:12743994 ).

Enzymes

Enzyme Details

1. Retinal dehydrogenase 1

General function:: Involved in oxidoreductase activity
Specific function:: Binds free retinal and cellular retinol-binding protein-bound retinal. Can convert/oxidize retinaldehyde to retinoic acid (By similarity).
Gene Name:: ALDH1A1
Uniprot ID:: P00352
Molecular weight:: 54861.44

Reactions

9-cis-Retinal + NAD + Water → 9-cis-Retinoic acid + NADH + Hydrogen Ion	details

Enzyme Details

2. Retinal dehydrogenase 2

General function:: Involved in oxidoreductase activity
Specific function:: Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Does metabolize octanal and decanal but does not metabolize citral, benzaldehyde, acetaldehyde and propanal efficiently (By similarity).
Gene Name:: ALDH1A2
Uniprot ID:: O94788
Molecular weight:: 54672.24

Reactions

9-cis-Retinal + NAD + Water → 9-cis-Retinoic acid + NADH + Hydrogen Ion	details

Enzyme Details

3. Alcohol dehydrogenase class-3

General function:: Involved in zinc ion binding
Specific function:: Class-III ADH is remarkably ineffective in oxidizing ethanol, but it readily catalyzes the oxidation of long-chain primary alcohols and the oxidation of S-(hydroxymethyl) glutathione.
Gene Name:: ADH5
Uniprot ID:: P11766
Molecular weight:: 39723.945

Enzyme Details

4. Alcohol dehydrogenase 1B

General function:: Involved in zinc ion binding
Specific function:: Not Available
Gene Name:: ADH1B
Uniprot ID:: P00325
Molecular weight:: 39835.17

Enzyme Details

5. Alcohol dehydrogenase class 4 mu/sigma chain

General function:: Involved in zinc ion binding
Specific function:: Could function in retinol oxidation for the synthesis of retinoic acid, a hormone important for cellular differentiation. Medium-chain (octanol) and aromatic (m-nitrobenzaldehyde) compounds are the best substrates. Ethanol is not a good substrate but at the high ethanol concentrations reached in the digestive tract, it plays a role in the ethanol oxidation and contributes to the first pass ethanol metabolism.
Gene Name:: ADH7
Uniprot ID:: P40394
Molecular weight:: 41480.985

Enzyme Details

6. Alcohol dehydrogenase 1A

General function:: Involved in zinc ion binding
Specific function:: Not Available
Gene Name:: ADH1A
Uniprot ID:: P07327
Molecular weight:: 39858.37

Enzyme Details

7. Alcohol dehydrogenase 6

General function:: Involved in zinc ion binding
Specific function:: Not Available
Gene Name:: ADH6
Uniprot ID:: P28332
Molecular weight:: 39072.275

Enzyme Details

8. Alcohol dehydrogenase 1C

General function:: Involved in zinc ion binding
Specific function:: Not Available
Gene Name:: ADH1C
Uniprot ID:: P00326
Molecular weight:: 39867.27

Enzyme Details

9. Beta,beta-carotene 15,15'-monooxygenase

General function:: Secondary metabolites biosynthesis, transport and catabolism
Specific function:: Symmetrically cleaves beta-carotene into two molecules of retinal. The reaction proceeds in three stages, epoxidation of the 15,15'-double bond, hydration of the double bond leading to ring opening, and oxidative cleavage of the diol formed.
Gene Name:: BCMO1
Uniprot ID:: Q9HAY6
Molecular weight:: 62636.69

Enzyme Details

10. Aldehyde dehydrogenase family 8 member A1

General function:: Involved in oxidoreductase activity
Specific function:: Converts 9-cis-retinal to 9-cis-retinoic acid. Has lower activity towards 13-cis-retinal. Has much lower activity towards all-trans-retinal. Has highest activity with benzaldehyde and decanal (in vitro). Has a preference for NAD, but shows considerable activity with NADP (in vitro)
Gene Name:: ALDH8A1
Uniprot ID:: Q9H2A2
Molecular weight:: 53400.9
