...wn and structural biologist John Bushweller. Using computer modeling, they docked the INS2 compound onto an enzyme in cells called PP2C. If INS2 could activate PP2C, it would trigger other events in cells activated by insulin. "INS2 was added and the purified PP2C enzyme was activated," Brautigan said.
