1 These four designs were chosen for further characterization.
2 A double mutant of XBP1-d2, in which serine at position 4e and tyrosine at position 5a were mutated to lysine and leucine, respectively.
3 Although ATF5 was used in the computational design, binding was tighter to ATF4, which shares 69.2% sequence identity with ATF5 in , , and positions.
