Methods for site-specific modification of proteins are in high demand. Reactions that yield bioconjugates should be quantitative, site-specific, and versatile with respect to nature and size of the biological/chemical targets involved, require minimal modification of the target, display acceptable kinetics under physiological conditions, and be orthogonal to other labeling methods. Sortase-mediated transpeptidation reactions meet these criteria. Here we describe the expression and purification conditions for two orthogonal sortase A enzymes and provide the protocol that allows functionalization of any given protein at its C-terminus or for select proteins at an internal site. Sortase-mediated reactions take only a few minutes, but reaction times can be extended to increase yields.
