These proteins include 3-oxoacyl-acyl carrier protein synthase 2,3-oxoacyl-acyl carrier protein reductase, the acetyl-CoA carboxylase biotin carboxylase subunit, the
acyl carrier protein, and NADH-dependent enoyl-acyl carrier protein reductase.
stewartii uses 3oxohexanoyl
acyl carrier protein and SAdenosylL Methionine (SAM) as substrates to make 3oxohexanoyl homoserine lactone (AHL) autoinducers.
The two carrier protein domains of DhbF were determined by sequence homology and it is worthwhile to notice that carrier proteins can be distinguished not only by the moiety they have to carry (acyl,
acyl carrier protein; aryl, ArCP; and peptidyl, PCP), but also by the signature of their highly conserved Ppant-binding site.
Battesti and Bouveret (6) have shown that during fatty acid starvation (p)ppGpp synthetase activity of SpoT is regulated through an interaction of the TGS domain of the enzyme with the
acyl carrier protein (ACP), a central co-factor in fatty acid biosynthesis.
