Value	2 times larger outside than inside the membrane
Organism	Unspecified

Comments	P.100 left column bottom paragraph: "Second, the fit predicts that membrane proteins behave sterically like objects that are 3-fold larger than their transmembrane region estimated in this work (the bulbosity factor), thus limiting their maximum membrane occupancy to one third. This value is plausible, given that the molecular structures of electron transport chain complexes are, on average, estimated to be 2-fold larger outside the membrane than within it (Table S1B)." Please note: organism identity is not specified, however it is probably E. coli.
