Extended Data Fig. 3.: Cryo-EM structural determination of the SAMTom40-early intermediate.
From: A multipoint guidance mechanism for β-barrel folding on the SAM complex
a, The cryo-EM density maps (contoured at 7.0σ) and the atomic models for indicated segments of Sam50 and Tom40 in the SAMTom40-early intermediate. The structures of Sam35 and Sam37 are essentially the same as those reported before17. b–d, Secondary structure diagrams of Tom40 and Sam50, forming a hybrid β-barrel in the SAMTom40-early intermediate (b), Sam35 (c), and Sam37 (d) are shown. The regions invisible or unresolved are indicated in grey.
