Fig. 5. Apo conformation of MtCorBΔC captured by R235L mutant.

Fig. 5

a Overall structure of MtCorBΔC R235L mutant. One chain is colored by domains. b Novel domain–domain contact between TMD and CBS-pair domain. c AHB binds to CBS-pair domain and competes for Mg2+-ATP site. d Large conformational change in the AHB and CBS-pair domains upon Mg2+-ATP binding. e The apo and ATP-bound structures are similar with differences limited to the AHB and α8 helix.
