Figure 3From: Regulation of osmoadaptation in the moderate halophile Halobacillus halophilus: chloride, glutamate and switching osmolyte strategiesThe proline operon of Halobacillus halophilus. The proline operon of Halobacillus halophilus comprises 3 genes encoding a pyrroline-5-carboxylate reductase (proH), a glutamate 5-kinase (proJ) and a glutamate 5-semialdehyde dehydrogenase (proA). The gene products are sufficient to synthesize proline from glutamate (Fig. 5).Back to article page
