摘要
(Graph Presented) Titinic strength: The mechanical resistance of titin domain I27 (see picture, left) was increased by substituting residues from a stronger homologue in regions of the protein important for mechanical strength (red). The unfolding profile of I27st (see picture, right) shows that the mechanical strength is significantly increased compared to wild-type I27 (black arrow). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
