I searched the Xplor-NIH mailing list to know how many modified amino acids are supported in Xplor-NIH. So far, I can see N-terminal acetylation and spin labeled (MTSL) cysteine are documented in the mailing list. I wonder to know if acetylated lysine, phosphorylated serine, threonine and methylation are also supported in Xplor-NIH. Here is the [...]

Density functional calculations of backbone 15N shielding tensors in beta-sheet and turn residues of protein G
Abstract We performed density functional calculations of backbone 15N shielding tensors in the regions of beta-sheet and turns of protein G. The calculations were carried out for all twenty-four beta-sheet residues and eight beta-turn residues in the protein GB3 and the results were compared with the available experimental data from solid-state and solution NMR measurements. Together with the alpha-helix data, our calculations cover 39 out of the 55 residues (or 71%) in GB3....

[KPWU blog] Install Xplor-NIH 2.26 on new iMac (10.6)
Install Xplor-NIH 2.26 on new iMac (10.6)
A short note for installation of xplor-nih 2.26 on iMac. Few months ago, I downloaded XPLOR-NIH 2.26 for Mac OS and installed it on my new iMac (core i3, 3.06 GHz). The default configuration script does not include “Intel Core i3″ *in the processor list (at xplor-nih-xxx/arch/getDarwinCPU). The solution to make the configuration is to http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=234&subd=kpwu&ref=&feed=1
