Protein-protein interaction of Wag31 molecules by the yeast two-hybrid system. The pJZ4-G and pHZ5-NRT clones with each wag31 Mtb allele were individually transformed into the RFY231 and the Y309 strains, respectively. Four independent colonies from each transformation were mated, and reporter phenotypes for protein-protein interaction were determined by quantitative measurements of β-galactosidase activity using the Yeast β-Galactosidase Assay Kit (Pierce). WT-WT, interaction between Wag31Mtb-Wag31Mtb; TA-TA, interaction between Wag31T73AMtb-Wag31T73AMtb; TE-TE, interaction between Wag31T73EMtb-Wag31T73EMtb; Vec-WT, control containing pHZ5-NRT-wag31 Mtb and pJZ4-G vector; Vec-Vec, control containing pHZ5-NRT and pJZ4-G vectors; Rv1102c-Rv1103c, positive control containing pHZ5-NRT-Rv1102c and pJZ4-G-Rv1103c [39]. Data shown are from a representative experiment done in duplicate, and data are represented as mean +/- SEM.
