== Function ==
 +
[https://www.uniprot.org/uniprot/FABH_STAAR FABH_STAAR] Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Catalyzes the first condensation reaction which initiates fatty acid synthesis and may therefore play a role in governing the total rate of fatty acid production. Possesses both acetoacetyl-ACP synthase and acetyl transacylase activities. Its substrate specificity determines the biosynthesis of branched-chain and/or straight-chain of fatty acids (By similarity).

== Publication Abstract from PubMed ==
 +
FabH (beta-ketoacyl-acyl carrier protein synthase III) is unique in that it initiates fatty acid biosynthesis, is inhibited by long-chain fatty acids providing means for feedback control of the process, and dictates the fatty acid profile of the organism by virtue of its substrate specificity. We report the crystal structures of bacterial FabH enzymes from four different pathogenic species: Enterococcus faecalis, Haemophilus influenzae, Staphylococcus aureus and Escherichia coli. Structural data on the enzyme from different species show important differences in the architecture of the substrate-binding sites that parallel the inter-species diversity in the substrate specificities of these enzymes.
