It's ubiquinol:cytochrome c oxidoreductase, or Complex III for short. <br /><br />It oxidises ubiquinol and reduces cytochrome c, using the free energy change to transfer protons to the mitochondrial intermembrane space (or bacterial periplasm), creating a combined electrical and osmotic gradient that can be tapped to generate ATP by allowing the protons to flow back through an ATPase. This mechanism underlies energy-conversion processes in organisms as diverse as chemoautotrophic bacteria and the possessors of plant chloroplasts and our own mitochondria. <br /><br />This nicely symmetric enzyme also appears on the cover of some biochemistry book, somewhere. <br />Allan Millernoreply@blogger.comtag:blogger.com,1999:blog-37148773.post-14311889678008393902012-08-20T20:36:13.167-04:002012-08-20T20:36:13.167-04:00Looks to me like the cytochrome bc1 complex (aka C...Looks to me like the cytochrome bc1 complex (aka Complex III, or ubiquinol-cytochrome c oxidoreductase).<br />Stephen Spiro, UT Dallas<br />stephen.spiro@utdallas.eduStephen Spirohttps://www.blogger.com/profile/08341481928402276287noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-7642974442867775822012-08-20T16:40:40.452-04:002012-08-20T16:40:40.452-04:00Complex III of the membrane-associated electron tr...Complex III of the membrane-associated electron transport chain found in mitochondria and in the membranes of bacteria.<br /><br />Easy one.Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.com
