Molecular characterization of the Escherichia coli htrD gene: cloning, sequence, regulation, and involvement with cytochrome d oxidase.

abstract：:Ferric reductase activity was examined in Azotobacter vinelandii and was found to be located in the cytoplasm. The specific activities of soluble cell extracts were not affected by the iron concentration of the growth medium; however, activity was inhibited by the presence of Zn2+ during cell growth and also by the ad...
