Protocol to evaluate translation inhibition in Candida species using fluorescence microscopy and flow cytometry

Translation inhibitors have therapeutic potential against Candida species. Here, we present a protocol to measure translation inhibition in Candida spp. We describe steps for employing an alkynylated methionine analog, L-homopropargylglycine (HPG), that becomes incorporated into newly synthesized proteins. We then detail procedures to perform a click reaction of the alkyne with a fluorescent azide, which is visualized using fluorescence microscopy and quantified by flow cytometry. For complete details on the use and execution of this protocol, please refer to Puumala et al.,¹ Fu et al.,² and Iyer et al.³.
