COMMENTARY 
LITERATURE
IMAGE
4-phenyl-5-phenylimino-[1,2,4]dithiazolidin-3-one
i.e. HR19; strong, synthase III
5-chloro-4-phenyl-[1,2]-dithiol-3-one
complete inhibition at 0.01 nM, synthase III; i.e. HR12
butyryl-CoA
-
synthase III mutants C122Aand C122Q: inhibition of decarboxylation activity in presence of
C75
-
a synthetic inhibitor of fatty acid synthase, inhibits also the beta-ketoacyl synthase, not in simple first order rate reaction, C75 is a competitive, irreversible inhibitor of the overall reaction, the beta-ketoacyl synthase activity and the enoyl reductase activity substrates do not protect the thioesterase activity of rat liver FAS from inactivation by C75, but malonyl-CoA and acetyl-CoA protect the FAS beta-ketoacyl synthase reaction from inactivation by C75 in a competitive manner, overview
isobutyryl-CoA
-
synthase III mutants C122Aand C122Q: inhibition of decarboxylation activity in presence of
isorhamnetin
3,5,7-trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chromen-4-one
N-(3-pyridinyl)-hexanamide
result of an in silicio screening, antimicrobial activity, binding to beta-ketoacyl-[acyl-carrier-protein] synthase I characterized by saturation-transfer difference NMR spectroscopy
thiolactomicin
thiolactomycin is an inhibitor of KAS I and inhibits bacterial cell growth through inhibition of the beta-ketoacyl-ACP synthase activity of type II fatty acids ynthases
[Acyl-carrier-protein]
-
wild-type synthase I and mutants, not mutants C163S and K328A, overview
cerulenin
-
analysis of the binding mechanism, mimicks the condensation transition state; FabB: inhibition is irreversible
cerulenin
forms two hydrogen bonding interactions with H333 and backbone amide hydrogen of G391 and a hydrophobic interaction with M197, F229, and F231
cerulenin
irreversible inhibitor of beta-ketoacyl-ACP synthases I and II but is not a selective anti-bacterial because it is also a potent inhibitor of the condensation reaction catalyzed by the mammalian multifunctional (type I) fatty-acidsynthase
cerulenin
-
antibiotic, protection by hexanoyl-[acyl-carrier-protein], decanoyl-[acyl-carrier-protein], and tetradecanoyl-[acyl-carrier-protein]
cerulenin
-
12-carbon mycotoxin, irreversible inhibition, binding motif; at 0.05 mM: wild-type is completely inactivated, mutant I108F and A193M show only 10% reduced activity
iodoacetamide
-
no inhibition of malonyl-[acyl-carrier-protein]-decarboxylation
iodoacetamide
-
acyl-[acyl-carrier-protein]-derivatives, e.g. acetyl-[acyl-carrier-protein], hexanoyl-CoA, octanoyl-CoA, decanoyl-CoA protect
iodoacetamide
-
acyl-[acyl-carrier-protein]-derivatives, e.g. acetyl-[acyl-carrier-protein], hexanoyl-CoA, octanoyl-CoA, decanoyl-CoA protect
iodoacetamide
-
acyl-[acyl-carrier-protein]-derivatives, e.g. acetyl-[acyl-carrier-protein], hexanoyl-CoA, octanoyl-CoA, decanoyl-CoA protect; synthase I and II
N-ethylmaleimide
-
no inhibition of malonyl-[acyl-carrier-protein]-decarboxylation
N-ethylmaleimide
-
no inhibition of malonyl-[acyl-carrier-protein]-decarboxylation
platencin
-
exhibits a broad-spectrum Gram-positive antibacterial activity through inhibition of fatty acid biosynthesis, targets the two essential proteins, beta-ketoacyl-[acyl carrier protein] synthase II and III, i.e. FabF and FabH, purified FabH IC50: 0.016 mM, overview
thiolactomycin
-
analysis of the binding mechanism, mimics malonyl-[acyl-carrier-protein]; FabB: inhibition is reversible, competitive
thiolactomycin
forms a hydrogen bonding with H333 and a hydrophobic interaction of Phe229 and Thr300 with ecKAS I
