Figure 6.

Cartoon and stick representation showing minor conformational adjustments in the N terminus of V7R and L8A proteins compared with WT myrMA. (a) For V7R, a salt bridge between Arg-7 and Glu-52 stabilizes the myr(s) form. (b) When compared with WT myrMA (green), substitution of Leu-8 with Ala (slate, c) creates a better cavity for the myristate group (orange) and allows for the terminal methyl of myristate group to pack closer to Trp-16 (firebrick).
