TL;DR: This work identifies the first point mutation (K49E) that dramatically disrupts 14-3-3ζ/ligand interactions and the parallel effects of this single point mutation on both Raf-1 binding and ExoS activation strongly suggest that diverse associated proteins share a common structural binding determinant on 14- 3- 3ζ.

TL;DR: Based on the principle of freezing point superposition, a model for predicting unfrozen water content is worked out and it can consider the influences of five factors: soil variation, water content, temperature, solution concentration and overburden pressure as discussed by the authors.
Abstract: Based on the principle of freezing point superposition, a model for predicting unfrozen water content is worked out and it can consider the influences of five factors: soil variation, water content, temperature, solution concentration and overburden pressure. The difference of values between determination and calculation is less than 3 %.

TL;DR: In this paper, a peptide ranging from residues 229 to 240 (ENESANEGYRFG) of D1 protein was synthesized by stepwise solid-phase method, and resolution enhancement techniques were combined with band curvefitting procedures to quantitate the FTIR spectra in the amide I' region (1700-1600 cm-1).
Abstract: A peptide ranging from residues 229 to 240 (ENESANEGYRFG) of D1 protein was synthesized by stepwise solid-phase method. Resolution enhancement techniques were combined with band curve-fitting procedures to quantitate the FTIR spectra in the amide I' region (1700-1600 cm-1). FTIR analysis showed that DCMU induced drastic structural modification with a relative decrease of the unordered structure and turns, and a substantial increase of α-helix, which indicated that a much more compact structure was formed when DCMU was applied. The results may reflect molecular information for the protective effect of DCMU against photoinhibition.
