OmpS38 is involved in anaerobic respiration.
(A) Respiration of various EAs by strains as indicated. Furamate, oxygen and TMAO (Fig. S2) were evaluated by measuring growth whereas ferric citrate, nitrate and FeO(OH) (Fig. S2) were estimated by measuring the levels of products as growth supported by these EAs was too low to be reliably monitored. ∆ompS38C represents the mutant carrying a copy of the gene for complementation. Error bars (less than 10% of the average), representing S.D. from three independent experiments, were omitted for clarity. (B) Production of OmpS38 and OmpA under conditions indicated. Cells of mid-log phase grown on indicated EAs were subjected to SDS-PAGE. Presented are representative results of three independent experiments. Production in cultures supported by nitrate under anaerobic conditions was not assayed because growth was too poor.
