Fig. 3. (A) Patterns of [³H]methyl-labeled proteins of the bas mutant strains in comparison with the wild type. Protein gels were exposed to X-ray films for 1 (lanes 1–6) or 2 (lane 7) weeks. Lanes: 1, wild type; 2, ΔΔ; 3, ΔbasB; 4, Ω; 5, ΔbasT; 6 and 7, basT_trunc. Arrows indicate the positions of BasT (a) and BasT_trunc (b). (B) Immunochemical detection of BasB in total protein extracts using anti-BasB antibodies. Lanes: 1, wild type; 2, ΔΔ; 3, ΔbasB; 4, Ω; 5, ΔbasT; 6 and 7, basT_trunc.
