Differential expression of NiFe uptake-type hydrogenase genes in Salmonella enterica serovar Typhimurium.

Salmonella enterica serovar Typhimurium possesses three similar NiFe hydrogenases important to its virulence. Here we show that the three hydrogenase operons hyb, hya and hyd are expressed under different environmental conditions and are subject to control by different regulatory proteins. Hydrogenase promoter-lacZ fusion plasmids were transferred into the… CONTINUE READING
