FIG. 8.

Catabolic destruction of l-glutamate (•) with the appearance of metabolic l-aspartate (○) by resting cells of Yersinia pestis strain KIM previously grown at 37°C in synthetic medium containing 25 mM l-glutamate and 100 mM Na⁺. (A) Lcr⁺ cells grown with 4.0 mM Ca²⁺, (B) Lcr⁺ cells grown without added Ca²⁺, (C) Lcr⁻ cells grown with 4.0 mM Ca²⁺, and (D) Lcr⁻ cells grown without added Ca²⁺.
