Infrared Probing of 4-Azidoproline Conformations Modulated by Azido Configurations

Kyung‐Koo Lee、Kwang-Hee Park、Cheonik Joo 等 9 位作者2012-04-18The Journal of Physical Chemistry B

4-Azidoproline (Azp) can tune the stability of the polyproline II (P(II)) conformation in collagen. The azido group in the 4R and 4S configurations stabilizes and destabilizes the P(II) conformation, respectively. To obtain insights into the dependence of the conformational stability on the azido configuration, we car…

Dynamic, Ligand-dependent Conformational Change Triggers Reaction of Ribose-1,5-bisphosphate Isomerase from Thermococcus kodakarensis KOD1

Akira Nakamura、M. Fujihashi、Riku Aono 等 10 位作者2012-04-18Journal of Biological Chemistry

Ribose-1,5-bisphosphate isomerase (R15Pi) is a novel enzyme recently identified as a member of an AMP metabolic pathway in archaea. The enzyme converts d-ribose 1,5-bisphosphate into ribulose 1,5-bisphosphate, providing the substrate for archaeal ribulose-1,5-bisphosphate carboxylase/oxygenases. We here report the cry…

Comment on “A comparison of the von Mises and Hencky equivalent strains for use in simple shear experiments”

Susumu Onaka2012-04-18The Philosophical Magazine A Journal of Theoretical Experimental and Applied Physics

Onaka has shown (2010) that the Hencky equivalent strain is the appropriate quantity to represent the degree of severe plastic deformation based on simple-shear deformation. In a recent paper, Shrivastava et al. have criticized (2011) the Onaka paper and stated that the Hencky formulation does not apply to large simpl…
