Cloning and expression in Escherichia coli of the gene encoding β‐C‐4‐oxygenase, that converts β‐carotene to the ketocarotenoid canthaxanthin in Haematococcus pluvialis

Open access
·1995·FEBS Letters

Abstract

In the green alga Haematococcus pluvialis the ketocarotenoid astaxanthin accumulates under stress conditions. Astaxanthin is a red carotenoid pigment which possess antioxidative activity. We have cloned the gene for β‐C‐4 oxygenase (β‐carotene ketolase) from the green algae H. pluvialis. The cloning method took advantage of a strain of E. coli which was genetically engineered to produce β‐carotene. An expression cDNA library of H. pluvialis was transfected to cells of this strain and visually screened for brown‐red pigmented colonies. One colony out of 100,000 transformants showed color change due to accumulation of canthaxanthin. The cDNA clone in this transformant colony encodes the enzyme β‐C‐4 oxygenase that catalyzes the conversion of β carotene to canthaxanthin via echinenone. This enzyme does not convert zeaxanthin to astaxanthin. It is concluded that in H. pluvialis astaxanthin is synthesized via canthaxanthin and therefore an additional enzyme is predicted, which converts canthaxanthin to astaxanthin.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
