In ongoing efforts to improve the coverage of the CGenFF program, version 2.1.0 of the CGenFF program extends support to the S-P bond found in the GTP-gamma like molecules. Bonded parameters and charge-distribution along the S-P bond were modeled using the CHARMM nucleic acid force-field patches for mono- and di-thio substitutions (toppar_all36_na_reactive_rna.str). Three new atom-types have been added to the CGenFF force-field: SG2P1, SG2P2 to support the mono- and di-thio substitutions, along with OG2S1 to model the terminal oxygen connected to the S-P bond.
