Pyochelin: novel structure of an iron-chelating growth promoter for Pseudomonas aeruginosa.
Open accessAbstract
Pyochelin, an endogenous growth promoter that solubilizes ferric iron, has been isolated from Pseudomonas aeruginosa, including clinical strains. The structure of pyochelin has been assigned as 2-(2-o-hydroxyphenyl-2-thiazolin-4-yl)-3-methylthiazolidine-4-carboxylic acid and is of a different type from those previously assigned to siderophores (siderochromes) from bacteria. The assignment rests on 1H and 13C NMR data, high-resolution (including field desorption) mass spectrometry, and spectroscopic properties of synthetic model compounds. Pyochelin is presumed to be biosynthesized from salicylic acid and two moles of cysteine.

“As presented in Section 3, P. aeruginosa produces two endogenous siderophores, a more energy demanding high affinity molecule, PVD [76] and a lower affinity siderophore, PCH [77].”

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.
