The pigments of Prochlorococcus marinus: The presence of divinylchlorophyll a and b in a marine procaryote
Abstract
The pigments of the recently isolated marine prochlorophyte Prochlorococcus marinus were characterized by modern chromatographic and spectroscopic analysis. The major photosynthetic pigment is 8‐desethyl, 8‐vinyl chlorophyll a. Accessory pigments are 8‐desethyl, 8‐vinyl chlorophyll b, zeaxanthin, α‐carotene, an unknown carotenoid, and possibly Mg 3,8 divinyl‐pheoporphyrin a5. Chl a is not present in this organism. P. marinus is the first wild‐type oxygenic phototroph that does not have Chl a as its major photosynthetic pigment and it is the only procaryote ∊‐cyclic carotenoids (α‐carotene). P. marinus demonstrates a range of biosynthetic abilities that will necessitate a re‐evaluation of the evolution of chlorophyll and carotenoid biosynthesis in pro‐ and eucaryotic phototrophs.

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.
