摘要：

One, two, three, whee! After transfer into the gas phase, the three-helix bundle protein KIX is sufficiently stabilized by electrostatic interactions to compensate for the loss of hydrophobic bonding. It thus retains its global fold on a timescale of more than 4 s. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
