New Type II Manumycins Produced by Streptomyces nodosus ssp. asukaensis and Their Biosynthesis.
Open accessAbstract
Five new type II manumycins, containing the hydroxyquinol mC7N unit, asukamycins A-II, B-II, C-II, D-II, E-II, were discovered in cultures of Streptomyces nodosus ssp. asukaensis. The biosynthetic origin of the type II manumycins from the type I compounds, containing an epoxyquinol mC7N unit, was deduced from the time course of production and proven by preparing [7'-13C]asukamycin A and demonstrating its incorporation into asukamycin A-II.

Manumycin polyketides possess a suite of electrophilic sites that could potentially react covalently with nucleophilic amino acids within proteins, such as cysteines.
“These molecules possess a suite of electrophilic sites that could potentially react covalently with nucleophilic amino acids within proteins, such as cysteines (Figure 1a) 19.”

Manumycin A has been shown to inhibit farnesyl transferase activity and sphingomyelinase activity.
“Manumycin A has also been show to inhibit farnesyl transferase activity and sphingomyelinase activity, but asukamycin is not known to inhibit these targets and its anti-cancer mechanism of action is unclear 19–23.”

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.
