How to identify L-Isomers and D-Isomers from PDB structures

PDB-tools

Hi,

Is there a easy way to identify whether a residual is a L-isomer or D-isomer in PDB structures? Either using PDB tools or other means? I know it can be found based on its angles but that would require writing custom code to parse.

Thanks

May-be some protein validation tools will report that. E.g. the PDB validation suite.

Our PDB-tools have nothing for that purpose.
