Here, we describe a protocol for incorporation of selenomethionine (SeMet) into proteins expressed in L. lactis. Incorporation efficiencies of SeMet in the membrane protein complex OpuA (an ABC transporter) and the soluble protein OppA, both from L. lactis, were monitored by mass spectrometry. Both proteins incorporated SeMet with high efficiencies (>90%), which greatly extends the usefulness of the expression host L. lactis for X-ray crystallography purposes. The crystal structure of ligand-free OppA was determined at 2.4 A resolution by a semiautomatic approach using selenium single-wavelength anomalous diffraction phasing.
