Ribbon representation and vulnerability (SEBH) pattern of subunit 1 from the cytochrome b-c1 complex. (a) Ribbon representation and (b) vulnerability (SEBH) pattern of subunit 1 from the cytochrome b-c1 complex (PDB.1KB9) . In b, red segments represent virtual protein backbone bonds, light-grey segments represent well protected backbone hydrogen bonds, and those green segments represent SEBHs. In the cytochrome complex, this protein adopts a highly vulnerable (ν = 57.3%) conformation.
