----------------------------------------------------------- | > Hellow, > My sequence was processed with SPDBV which add NH3 and COO- at the Nterminal and Cterminal respectively thereby MD simulation was carried out using GROMACS versions of 3.3.2 and 4.0. The system was working well. > Now I would like to add protecting groups i.e.acetyl group (CH3CO) and Nmethyl (NHCH3) at the N and C terminal respectively instead of NH3 and COO- using Gromacs 4.0. > Kindly suggest me needful action for the said construction. Or kindly suggest the software which can construct like CH3CO-Gly-trp-lys- - - - - - - - NHCH3 thereby getting output file can be used by GROMACS 4.o for completing my MD of the molecuel having such a sequence any like CH3CO-Gly-trp-lys- - - - - - - - NHCH3 . | ----------------------------------------------------------- You will need some non-GROMACS software to do this.
