Mutant derivatives of a <i>thiC1129 panE</i>::<i>Cm</i> strain grow on minimal glucose medium.

<p>The parental <i>thiC panE</i> strain fails to grow on minimal glucose medium (filled circles), but a suppressor derivative (DM13897) grows well (filled triangles). Growth of the parental strain was restored by the addition of thiamine (100 nm) (open circles) or pantothenate (100 μM). Growth data show representative experiment repeated with three independent cultures.
