HHsearch alignment for GI: 254781042 and conserved domain: cd03497
>cd03497 SQR_TypeB_1_TM Succinate:quinone oxidoreductase (SQR) Type B subfamily 1, transmembrane subunit; composed of proteins similar to Bacillus subtilis SQR. SQR catalyzes the oxidation of succinate to fumarate coupled to the reduction of quinone to quinol. Bacillus subtilis SQR reduces low potential quinones such as menaquinone. SQR is also called succinate dehydrogenase (Sdh) or Complex II and is part of the citric acid cycle and the aerobic respiratory chain. SQR is composed of a flavoprotein catalytic subunit, an iron-sulfur protein and one or two hydrophobic transmembrane subunits. Members of this subfamily are classified as Type B as they contain one transmembrane subunit and two heme groups. The heme and quinone binding sites reside on the transmembrane subunit. The transmembrane subunit of Bacillus subtilis SQR is also called Sdh cytochrome b558 subunit. The structural arrangement allows efficient electron transfer between the catalytic subunit, through iron-sulfur centers,
