Hydroxamates are also a bit tricky chemically; their chemistry is different than carboxylates or amides, so parameters for the ASP or ASN side chains are unlikely to work. There are also some really old papers from Gilchrist & Jencks on alpha-effect nucleophiles that are good examples of why hydrox

Maybe, one could also think about calculating the RESP charges via QM, e.g. with Gaussian...Further parameters, like force-constants and dihedrals could also be evaluated... But what's against an expensive random number generator? I fear I'm doing this with FEP all day long...;) Raja: We are (
