Abstract

Carotenoids with cyclic end groups are essential components of the photosynthetic membrane in all known oxygenic photosynthetic organisms. These yellow pigments serve the vital role of protecting against potentially lethal photo‐oxidative damage. Many of the enzymes and genes of the carotenoid biosynthetic pathway in cyanobacteria, algae and plants remain to be isolated or identified. We have cloned a cyanobacterial gene encoding lycopene cyclase, an enzyme that converts the acyclic carotenoid lycopene to the bicyclic molecule β‐carotene. The gene was identified through the use of an experimental herbicide, 2‐(4‐methylphenoxy)triethylamine hydrochloride (MPTA), that prevents the cyclization of lycopene in plants and cyanobacteria. Chemically‐induced mutants of the cyanobacterium Synechococcus sp. PCC7942 were selected for resistance to MPTA, and a mutation responsible for this resistance was mapped to a genomic DNA region of 200 bp by genetic complementation of the resistance in wild‐type cells. A 1.5 kb genomic DNA fragment containing this MPTA‐resistance mutation was expressed in a lycopene‐accumulating strain of Escherichia coli. The conversion of lycopene to β‐carotene in these cells demonstrated that this fragment encodes the enzyme lycopene cyclase. The results indicate that a single gene product, designated lcy, catalyzes both of the cyclization reactions that are required to produceβ‐carotene from lycopene, and prove that this enzyme is a target site of the herbicide MPTA. The cloned cyanobacterial lcy gene hybridized well with genomic DNA from eukaryotic algae, thus it will enable the identification and cloning of homologous genes for lycopene cyclase in algae and plants.

  • Lycopene is transformed into β-carotene by lycopene-β-cyclase, which depends on NADPH.

    “Lycopene, a compound with a red hue conferred by a set of 11 conjugated double bonds, is transformed into β,β-carotene by an enzyme known as lycopene-β-cyclase.126,127 Although not a reaction that involves net redox changes, the cyclization performed by lycopene-β-cyclase is dependent on an NAPDH cofactor.128”

    From Chemistry of the Retinoid (Visual) Cycle (2014) · cites this paper as [127]

    Citation 128 is attached to the NADPH-dependence claim, not the preceding conversion claim. The Introduction and Discussion describe lycopene cyclase converting lycopene to β-carotene, but the passages found when searching for NADPH, reducing cofactors, and cofactor requirements do not address whether that reaction depends on NADPH.

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.
