HHsearch alignment for GI: 254781041 and conserved domain: cd03526
>cd03526 SQR_QFR_TypeB_TM Succinate:quinone oxidoreductase (SQR) and Quinol:fumarate reductase (QFR) Type B subfamily, transmembrane subunit; SQR catalyzes the oxidation of succinate to fumarate coupled to the reduction of quinone to quinol, while QFR catalyzes the reverse reaction. SQR, also called succinate dehydrogenase or Complex II, is part of the citric acid cycle and the aerobic respiratory chain, while QFR is involved in anaerobic respiration with fumarate as the terminal electron acceptor. SQR and QFR share a common subunit arrangement, composed of a flavoprotein catalytic subunit, an iron-sulfur protein and one or two hydrophobic transmembrane subunits. Type B proteins contain one transmembrane subunit and two heme groups. The heme and quinone binding sites reside in the transmembrane subunits. The structural arrangement allows efficient electron transfer between the catalytic subunit, through iron-sulfur centers, and the transmembrane subunit containing the electron donor/acc
