THE LINKER OF DES-GLU84 CALMODULIN IS BENT AS SEEN IN THE CRYSTAL STRUCTURETHE LINKER OF DES-GLU84 CALMODULIN IS BENT AS SEEN IN THE CRYSTAL STRUCTURE

Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of a mutant calmodulin (CaM) lacking Glu-84 has been refined to R = 0.23 using data measured to 2.9-A resolution. In native CaM the central helix is fully extended, and the molecule is dumbbell shaped. In contrast, the deletion of Glu-84 causes a bend of 95 degrees in the linker region of the central helix at Ile-85. However, EF-hand domains 1 and 2 (lobe 1,2) do not touch lobe 3,4. The length, by alpha-carbon separation, of des-Glu84-CaM is 56 A; that of native CaM is 64 A. The shape of des-Glu84-CaM is similar to that of native CaM, as it is bound to the target peptide of myosin light-chain kinase. This result supports the proposal that the linker region of the central helix of CaM functions as a flexible tether. The linker of des-Glu84-calmodulin is bent.,Raghunathan S, Chandross RJ, Cheng BP, Persechini A, Sobottka SE, Kretsinger RH Proc Natl Acad Sci U S A. 1993 Jul 15;90(14):6869-73.
