Description

This floe performs mutations on input antibody design units. Multiple independent mutations are allowed and are generated using the OEMutateResidue functionality in the order that they appear in the parameter field.

Optionally, and after mutation(s) are completed, functionality in OEFF is used to perform an energy minimization on the antibody structure.

Limitations: Mutations can only be performed on the antibody protein. Mutation on the antigen or any design unit Other Proteins are not allowed at this time.

Potential Input Sources: Antibody Sequences to 3D Models Floe, Antibody Experimental Structure Prep Floe

Minimization Parameters

Sequence Numbering Scheme (numbering_scheme): This parameter sets the numbering scheme applied to antibodies.

  • Required

  • Type: string

  • Default: IMGT

  • Choices: [‘IMGT’, ‘Chothia’, ‘Martin’, ‘Kabat’]

Run Minimization (run_minimize): Option to run structure minimization.

  • Required

  • Type: boolean

  • Default: True

  • Choices: [True, False]

CDR Selection (cdr_selection): CDR loop regions to be flexible during structure relaxation.If none are selected entire system is marked flexible
