Immunoblot analysis of GlxA maturation in S. lividans TK24 and tat mutant strains grown for for 2 days on R5 medium (a) or grown for 24 h in TSBS medium (b) in the presence (+) or absence (−) of 10 µM CuSO4. The two bands indicated with the solid arrows represent GlxA, the upper band being immature GlxA (no Tyr–Cys cross-link) and the lower band being mature GlxA (with Tyr–Cys cross-link). The band indicated with a dashed arrow indicates EF-Tu, which serves as a control for the total amount of protein loaded on the gel. Molecular weight markers are indicated in kDa.
