Figure 3
Structural homology and surface representation of the enclosed cavities in MSMEG_0317Δ. (a) Comparison of the MSMEG_0317Δ fold with the CD36 superfamily of scavenger receptor proteins, including the human lysosomal integral membrane protein 2 (LIMP-2) and CD36, a fatty-acid transporter, which show an extended asymmetric β-barrel core. (b) Comparison of the MSMEG_0317Δ enclosed cavities with the CD36 cavity which binds palmitic acid. (c) Close-up of MSMEG_0317Δ cavity 1 entrance 1. (d) Close-up of MSMEG_0317Δ cavity 1 entrance 2. (e) Close-up of MSMEG_0317Δ cavity 2. Hydrogen-bond and salt-bridge interactions are shown as black dashed lines. See also Supplementary Fig. S5. |
