Anaerobic Respiration - Exercise #3
E. coli contains three lactate dehydrogenases. One is used to ferment pyruvate to lactate and the other two are used as electron donors in aerobic respiration.
- Name the genes encoding the three lactate dehydrogenases and state what process the enzyme is involved in.
- The lldD gene is part of an operon. Which other genes are present and what is the function of their gene products?
- Under what environmental conditions is lldD repressed? What protein(s)/molecule(s) repress its expression?
