In Escherichia coli and many other bacteria, two small, hydrophobic, mutually homologous subunits of succinate dehydrogenase (a TCA cycle enzyme) are SdhC and SdhD []. This entry is the SdhD, the hydrophobic membrane anchor protein. SdhC is apocytochrome b558, which also plays a role in anchoring the complex.
In Escherichia coli and many other bacteria, two small, hydrophobic, mutually homologous subunits of succinate dehydrogenase (a TCA cycle enzyme) are SdhC and SdhD. Both SdhC and SdhD participate in anchoring the complex. This entry represents SdhC, the cytochrome b subunit, also called b556 in bacteria.Mycobacterium contains two operons which are predicted to encode succinate dehydrogenase enzymes (Sdh-1 and Sdh-2). SdhC is encoded in the operon sdhCDAB for Sdh-2. Sdh1 (and not Sdh2) seems to be the primary aerobic succinate dehydrogenase of M. tuberculosis [].
In Escherichia coli and many other bacteria, two small, hydrophobic, mutually homologous subunits of succinate dehydrogenase (a TCA cycle enzyme) are SdhC and SdhD. This entry represents SdhC, the cytochrome b subunit, called b556 in bacteria and b560 in mitochondria. SdhD (see ) is called the hydrophobic membrane anchor subunit, although both SdhC and SdhD participate in anchoring the complex. In some bacteria, this cytochrome b subunit is replaced my a member of the cytochrome b558 family (see ).
