Mapping Functions¶

These functions convert one residue into another. They are primarily used for standard and modified amino acids.

CopyResidue(src_res, dst_res, editor)¶

This function copies atoms from a source residue to a destination residue. It calls either CopyConserved() or CopyNonConserved() depending on whether the residues are identical or not.

Parameters:

• src_res (ResidueHandle) – The source residue.

• dst_res (ResidueHandle) – The destination residue.

• editor (EntityEditor) – The editor to use for the copy operation.

Returns:

The number of atoms copied.

CopyConserved(src_res, dst_res, editor)¶

This function copies atoms under the assumption that the source and destination residues are identical or that the source is a modified version of the destination. It handles modifications and converts selenium to sulfur for specific residues.

Parameters:

• src_res (ResidueHandle) – The source residue.

• dst_res (ResidueHandle) – The destination residue.

• editor (EntityEditor) – The editor to use for the copy operation.

Returns:

The number of atoms copied.

CopyNonConserved(src_res, dst_res, editor)¶

This function copies heavy backbone atoms and CBeta from the source to the destination.

Parameters:

• src_res (ResidueHandle) – The source residue.

• dst_res (ResidueHandle) – The destination residue.

• editor (EntityEditor) – The editor to use for the copy operation.

Returns:

The number of atoms copied.
