Modify allows the user to make common amino acid and nucleotide modifications by mouse actions. Hover text above each atom gives the available options if any including methylation on nucleosides, single-bond oxygens, and nitrogens, hydroxylation of PRO, formylation of MET, ribose/deoxyribose interconversion, phosphorylation of SER, THR, TYR and HIS, and nucleotide modifications to generate pseudouridine, dihyrouridine, inosine, and xanthine.

Modifications indicated with 1: are performed with ALT-CLICK on the atom. Modifications indicated with 2: are performed with SHIFT-CLICK on the atom.

See Convert for a script to replace one amino-acid with another or one nucleotide with another.

After a modification adding atoms, the hover text on those atoms includes 'X' to remove the modification. Note also that the desired modification may be presented in the hover text on only just one or a few of the atoms of the residue to be modified and you may have to look around to find it.

Some features unrelated to modification have been placed here as well to serve other Plico functions. Water molecules may be added and moved around perhaps to serve as pivot points for Tug when no other atoms are where the pivot point is wanted.

Also the Jmol parameters allowMoveAtoms, allowRotateSelected, and dragSelected are set true while modify is active to allow free rotation and translation of selected atoms where ALT-DRAG rotates the selection and ALT-SHIFT-DRAG moves it. Note that the select chain option in Modify selects all atoms connected to the clicked atom, not those sharing the chain label with the clicked atom.

Modify is a member of the Plico suite of protein folding tools described here. It may be installed and accessed as a macro with the file:

Title=PLICO Modify
Script=script <path to your scripts directory>/modify.spt;plico_modify

saved as plicoModify.macro in your .jmol/macros directory as described in Macro.

Copy and paste the following to a text editor and save to your scripts directory as modify.spt:
