Figure 3. Model of MAT R606A Mutant with Covalently-docked Decanoyl Moiety.

Figure 3

A. The decanoyl group is in thioester linkage with Ser 581. Replacement of Arg by Ala allows binding of the decanoyl chain. Location of Arg606 in the WT enzyme, which obstructs entry of long acyl chains, is also shown for comparison. B. Interaction of the decanoyl chain (yellow) with hydrophobic side chains (green).
