3B). R526 from the loop among αJ and αI anchors the C-terminal percentage of the activation loop by forming a salt bridge with E458 at the base of αEF. Q459 stabilizes the HRD motif by a hydrogen bond to the principle chain carbonyl of R413. The idea with the activation section is stabilized by a hydrogen bond among Y454 and E480 from αF. insid
