Figure 4From: Production of Diamino propionic acid ammonia lyase by a new strain of Salmonella typhimurium PU011Effect of Temperature on the Stability of DAP ammonia lyase. The crude enzyme extract was incubated at various temperatures ranging between 20°C – 60°C in 10 mM phosphate buffer and the enzyme activity measured. The enzyme activity is expressed as (U/mg) × 10-3.Back to article page
