Figure 2

Domains are labeled and colored as follows: Pap, blue; KR1, pink; KR2, yellow; KR3, orange; KR4, green; KR5, purple; SP, cyan. The chloride ions (Cl) 1 and 2 are in the interface KR4/PAp and KR2/SP, respectively, and are shown as spheres. Two other chloride ions 3 and 4, bind to the KR2 and SP domain, respectively. The position of the activation loop is marked with a red sphere. The LR of KR1 is marked with an asterisk (*). Figure taken from Law et al. (2012) [38].
