RESUMO
Immunological methods were used to obtain information about Escherichia coli heme proteins. There is a membrane-bound catalase which consists of a single subunit (as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis) which is also present in the soluble fraction. Antibodies raised against purified, soluble cytochrome b562 showed that this cytochrome is not related to any of the membrane-bound cytochromes, including the b562 component of the cytochrome o complex. Cytochrome b556 is immunologically unrelated to the cytochrome b556 NR associated with the nitrate reductase system. Cytochrome b556 and cytochrome o are not present in a constant ratio in the membrane.
