Extended Data Fig. 4: Structural comparison among GtACR1, HsBR, HsHR, C1C2 and CrChR2.
From: Crystal structure of the natural anion-conducting channelrhodopsin GtACR1
a, b, Side view and extracellular view of the superimposed transmembrane regions of GtACR1 (blue) and HsBR (cyan) (a), GtACR1 (blue) and HsHR (beige) (b), C1C2 (green) and CrChR2 (yellow) (c). The ATRs are shown as stick models, and are coloured orange (GtACR1), salmon (HsBR), light-yellow (HsHR), green (C1C2) and yellow (CrChR2).
