Deletion of glyA, ltaE, and tdcB but not tdh partially suppresses zipA1 mutant thermosensitivity. The effects of suppressing zipA1 mutant thermosensitivity were determined by growing WM5337 (A) and zipA1 mutants lacking glyA (B), ltaE (C), tdh (D), or tdcB (E) in LB broth for 1.5 h at 37°C. Scale bar, 4 μm.
