Escherichia coli molybdoenzymes can be activated by protein FA from several gram-negative bacteria.
Six Gram-negative bacteria (Klebsiella pneumoniae, Erwinia chrysanthemi, Proteus vulgaris, Serratia marescens, Salmonella typhimurium, and Pseudomonas aeruginosa) were shown to contain an FA-type protein capable of activating aponitrate reductase, apotrimethylamine N-oxide reductase and apoformate dehydrogenase of Escherichia coli. Protein FA activity was highest in Erwinia chrysanthemi and lowest in Pseudomonas aeruginosa. All the species also contained the low-Mr (less than or equal to 1500) heat-resistant material previously reported to be necessary for the protein-FA-dependent activation of E. coli chlB nitrate reductase.
