A protocol for selective and site-specific enzymatic labeling of proteins is described. The method exploits the protein co-/post-translational modification known as myristoylation, the transfer of myristic acid (a 14-carbon saturated fatty acid) to an N-terminal glycine catalyzed by the enzyme

The gut microbiota can modulate human metabolism through interactions with macronutrients. However, microbiota-diet-host interactions are difficult to study because bacteria interact in complex food webs in concert with the host, and many of the bacteria are not yet characterized. To
