Comments on 3awr » Mitochondrial import receptor subunit TOM20, 59-126, with presequence peptide
N-terminal transmembrane helix was removed; this crystal structure provides correct orientation of presequence helix. Some other structures provide presequence helix with engineered SS bond, which results in incorrect oreintation of the helix and alternative orientation of whole structure with respect to membrane.
